Q:What is the difference between B and H fields (magnetic fields ) of a material? Please explain a littleThanks in advance!: The H field corresponds to what is called the magnetic field strength. It is measured in amps / meter (A/m). That is to say it is caused by a current and exists in the space around the current independent of the material occupying the space. H will generally be stronger near to the current and will diminish in strength with distance from the current. In free space or in air the B field represents magnetic flux density which is given in units of Tesla by B μ?.H where μ? is the absolute magnetic permeability of free space and 4π10^-7. More magnetic flux can be produced by the same H value in certain (magnetic) materials, notably iron, and this is accounted by introducing another factor, the relative permeability μr, giving B μ?.μr.H for magnetic materials. μr can take values of over 1000 which makes iron very attractive to use in devices (like transformers) which employ magnetic fields. Without using iron such devices would be physically much larger.

Q:A. SoftB. PermanentC. HardD. Brittle: The only dangers that I know of that a rat faces when it runs on a wheel is injury to its tail and feet. I've never heard of a rat breaking its back when running on a wheel. Though you will want to make sure its big enough and there aren't holes in the surface they run on that are big enough for their toes/feet to get stuck in.

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.

Q:explain why some materials are magnetic and some are nonmagnetic?: These materials have areas within them call domains. Each domain has a magnetization that is pointed in a certain direction; when groups of domains are pointed in the same direction, the material is magnetized in that area (in the direction the domains are pointing).

Q:What kinds of mechanical items we be able to bring back on line first? How would the new electric cars fare? What would be the effective range and effect of a100 kilo-ton bomb at this altitude? ar 40,000? at 30,000? at 20,000? Could a steam vehicle like the old Stanley Steamer be constructed out of non-magnetic materials to serve as transport while the effect is at its zenith?: The emp effect last for only milliseconds, much much less than one second. EMP bombs are NOT highly explosive. They do very little damage from the explosive force. The damage is ALL done from the EMP. talking about an EMP of 100 kilo-tons is senseless. An EMP bomb depends on a simple law of physics: If a magnetic field is moved around a coil of wire, an electrical current will be generated. -- AND -- The bigger the magnetic field, the large the electric current. A coil does not have to be all coiled up! A coil of wire COULD be a simple extension cord, or the high-tension lines on those big metal supports. The idea of an EMP is to generate a HUGE magnetic field. This field will generate a LARGE voltage in ANY electronic device -- thus frying it. Such an EMP would fry every chip in a computer or cell phone or laptop. It could melt all the wires in an automobile or airplane. ANYTHING with wires in it will be damaged -- light bulbs, televisions ets, toasters, automobiles, generators, hair dryers. computers, cell phones, and so on. ANY alectronic device will be damage, and probably made non-repairable. Small devices like cell phones could actually melt, or the batteries could catch fire or explode The OLDER a device is (like a car) the more likely it is to SURVIVE. An OLD model car, like from the 1970s, doesn't have all those new fangled computers and such in it. It might be repaired with some new spark plug wires and a new alternator. Something like a Prius would be totally lost. Some electric cars use motors in the wheels. Those motors could actually catch the tires on fire! A bicycle, having NO electric parts, would not be damaged! Thus, our first form of transportation to get back oon live will be walking, horse and buggy, and bicycles.

Q:The shield is to short-circuit the flux around the movement.A) ParamagneticB) DiamagneticC) Ferromagnetic: should be paramagnetic because there is no charge/valence electrons on the atom(s)

Q:Will cobalt absorb a magnetic field better than steel or iron because it is a denser ferromagnetic material? Please Help! Thanks in advance!: lLike Iron, it depends on the form that the cobalt is in. If you look at the standard standards used in magnetic susceptability, you will see a cobalt compound which has a low sussceptability. (sp?). You will also see lots of alloys the contain cobalt that are excellent magnets.

Q:Everyone knows that iron (metal) has magnetic properties. But why doesn‘t Ferric ammonium sulfate?There are many compounds that contain iron that have no magnetic properties. Why? Why are the magnetic properties also chemical properties? If you heat a compound and drive off another element, have you created a potential magnet? What happens if you slowly heat or cool a magnet. Are there potential magnet transition temperatures for an iron based compound? Are some endo and some exothermic reactions capable of creating potential magnetic compounds? Can magnetic fields cause chemical reactions? Are there any biochemical magnets?: It all because of the structure of the iron atom. The way the electrons are grouped together makes one side of the atom have a high positive charge, and the other a high negative one. When this little groups of particles are lined up, usually by an external force (magnets, current, electric fields, etc) all this positive and negative charges create a magnetic field by itself. When you add other elements to iron to create different compounds, the electric charges get more balanced and thus you don't get those groups of positive and negative charge. Thus, you don't get the magnetic properties. Hope this explanation makes sense. By the way, if the magnetic field is strong enough, even those materials considered non-magnetic can be affected. If I remember well, a university in the Netherlands was able to make a frog levitate using a powerful electromagnet of about 16 Teslas in a lab (your standard fridge magnet has only 0.005 Teslas).

Q:What is the difference between NdFeB and ferrite in magnetic materials?: For example, the price of NdFeB is very expensive, ferrite is very cheapFor example, temperature resistance: ferrite is very good, NdFeB ordinary only 80 degrees

Q:How to judge whether a metal material is non-magnetic or magnetic? Such as stainless steel, what testing instruments?: Such as stainless steel, iron alloy is inevitable, so there must be a magnetic material, magnetic material, but I don't know whether you said it is magnetic, if this is the case, there must be a permanent magnet magnetizing the magnetic, soft magnetic material is not magnetic, simple experimental materials can be used close to the pin, if can suck, prove the existence of some residual magnetic materials!!!
