Q: You have been given the task of describing the theory of magnetic domains to a class of 5th graders. You have enough large paper arrows to give one to each student. Describe your plan to show them the domain nature of - A non-magnetic material - A permanent magnet - An electromagnetRemember that your description of the activities should be about the domains of the magnet and not its polarity.: the web page (below) provides: A magnetic domain is region in which the magnetic fields of atoms are grouped together and aligned. In the experiment below, the magnetic domains are indicated by the arrows in the metal material. You can think of magnetic domains as miniature magnets within a material. In an unmagnetized object, like the initial piece of metal in our experiment, all the magnetic domains are pointing in different directions. But, when the metal became magnetized, which is what happens when it is rubbed with a strong magnet, all like magnetic poles lined up and pointed in the same direction. The metal became a magnet. It would quickly become unmagnetized when its magnetic domains returned to a random order. The metal in our experiment is a soft ferromagnetic material, which means that it is easily magnetized but may not retain its magnetism very long. see picture at web page too!

Q: We were asked to do a research on Application of Magnetic Materials in the Electronics Industry. That is reasonably easy enough but of course we were asked to include:Raw Materials UsedProperties (of material)Advantage/Disadvantage (of material)Specific Example, Illustrations and DiagramsMy problem is I can‘t tell what exactly does raw materials mean. I only found that there are three classifications namely: Diamagnetic, Paramagnetic, and Ferromagnetic Materials. Now that isn‘t exactly raw materials and when I search for them I only manage to turn up their function and concepts; no examples. Any useful links? And any tips on how to do this research? Any help would be appreciated, seeing as we were asked to do this HANDWRITTEN (god knows only why) with 10 pages as minimum, I really need help as fast as I could get.: Magnetic materials used in the electronics industry would be mostly (perhaps exclusively) ferromagnetic materials. The materials would be alloys and ferrites containing various elements like iron, nickel, cobalt, aluminum, neodymium and samarium. There are many applications for both permanent magnets and materials that have magnetic properties. You can find a lot of information in the pedia articles listed below. Additional information can be found by following links in those articles and by searching terms used in those articles. PS1: The above mentioned elements are used in permanent magnets. Additional elements used in ferrites and ceramic magnets include zinc, barium, manganese, oxygen and strontium. Silicon is the essential element in addition to iron in silicon steel.

Q: why are some materials magnetic and not others?: This may be surprising to some, but all matter is magnetic. It's just that some materials are much more magnetic than others. The main distinction is that in some materials there is no collective interaction of atomic magnetic moments, whereas in other materials there is a very strong interaction between atomic moments. The magnetic behavior of materials can be classified into the following five major groups: 1. Diamagnetism 2. Paramagnetism 3. Ferromagnetism 4. Ferrimagnetism 5. Antiferromagnetism Magnetic Properties of some common minerals Materials in the first two groups are those that exhibit no collective magnetic interactions and are not magnetically ordered. Materials in the last three groups exhibit long-range magnetic order below a certain critical temperature. Ferromagnetic and ferrimagnetic materials are usually what we consider as being magnetic (ie., behaving like iron). The remaining three are so weakly magnetic that they are usually thought of as nonmagnetic. cc

Q: I know diamagnetic materials like copper, brass, aluminum will but I need to know how much heat for electromagnetic energy induced. Anybody know that?: Hysteresis When a ferromagnetic material is magnetized in one direction, it will not relax back to zero magnetization when the imposed magnetizing field is removed. It must be driven back to zero by a field in the opposite direction. If an alternating magnetic field is applied to the material, its magnetization will trace out a loop called a hysteresis loop. The lack of retraceability of the magnetization curve is the property called hysteresis and it is related to the existence of magnetic domains in the material. Once the magnetic domains are reoriented, it takes some energy to turn them back again. This property of ferrromagnetic materials is useful as a magnetic memory. Some compositions of ferromagnetic materials will retain an imposed magnetization indefinitely and are useful as permanent magnets. The magnetic memory aspects of iron and chromium oxides make them useful in audio tape recording and for the magnetic storage of data on computer disks. Magnetic method has been used to evaluate the volume percentage of α' martensitic phase in austenitic stainless steels by measuring saturation magnetization, and it is said to be a candidate NDE method. However, nondestructive detection of saturation magnetization without high magnetic field is difficult. In the current work, we present a NDE method for evaluating the magnetic properties of strain induced α' martensitic phase. Low field hysteresis loops of an austenitic stainless steels type SUS 304 after cold rolling were measured by using a yoke sensor. The results show that the initial permeability μi and the relative coercive field Hcl calculated by low field hysteresis loop analysis keep monotonic relation with saturation magnetization and coercive force measured by VSM, respectively. By this method, it is possible to characterize the volume content and particle properties of α' martensitic phase in stainless steels. Answer: YES

Q: what makes store buzzers go off? do the bar codes make them go off as well as the magnetic things?: I think most of them work on the principle of induction. There's a litte coil or loop of metal in most of the tags, and when this passes through the barriers at the door, it sets off the alarm.

COILS? Type of electricity when charges are sitting on the surface (6 letters) ???????STATIC? The type of pipe in the forensics crime (5 letters) . any more details?

Q: in general steel material is used as core in electromagnets.but it is attracted by magnet.i want to know is there any material(non magnetic material)which can be used as a core,at the same time it can give same electromagnetic strenght as that of steel as a core.: i thought they used steel or iron cores because they have a high magnetic permeability(low resistance to magnetism), not for structural strength.

Q: build a magnetic counter part to electronic circuits? If monopoles did exist, do you think it would be possible to use them to create a different type of communications and perhaps even transportation systems? I wonder what a monopole circuit would look like when compared to an electrical circuit.Best regards: It Goes against the law of physics to isolate a Magnetic Pole. So its impossible to say what could or could not be achieved as a consequence.

Q: I would like to put a magnetic wall in my room. In my old house, I had a wall that I bought the paint for. However; I just want this to be a temporary do-it-yourself project. Is there a thin piece of metal I could hang up or what are some ideas??: Since you are familiar with the magnetic paint, you could paint a sheet of thin hardboard (sometimes called masonite) and attach that to the wall by screwing into the studs or using fasteners made for hollow walls then just fill the holes when you move. (I am assuming you live near a building materials or home improvement store and that you have hollow, sheetrock walls that are typical in the US.) You could also glue it on with contact or construction adhesive, but that would be hard to remove. A 4 foot by 8 foot sheet of 1/8 thick tempered hardboard at my nearby Home Depot costs about $6.50 For more flexibility you could use sheets of pegboard ($11.50 at my Home Depot) and then you would have both a magnetic surface and a pegboard surface for which you can get hooks and accessories to hang things from. You can also buy sheet metal (Google sheet metal in your local area for suppliers) and attach it to your wall with screws in the same way as the wood sheet. If you get the sheet metal you should have them roll or bend the edges over so that you don't have sharp edges to worry about getting cut by when you install it.

Q: Does ferromagnetic material have a great influence on its temperature? What is the high temperature and low temperature?: Influence of temperature on the characteristics of magnetic core inductance, obtained under different temperature conditions the characteristic is not the same, the general operating temperature below 105 degrees. It features high temperature and then decreased significantly, high magnetic loss.
