Q: How do you make a magnetic substance into a magnet?: A magnetic substance already has a magnetic field.A magnet is another magnetic substance with a stronger magnetic field. When the two Fields intersects they lock in forming a magnetic force. The magnetic Energy is the Result of the product of the magnetic power and the time that the magnetic power is applied to a magnetic mass. A magnet get its Magnetic Energy for the same reason that the Earth gets its Gravitational Energy. Example; a very small stone is dropped from a helicopter to a gravitational mass called Earth. AS the stone falls to the Ground it gets stuck to the Earth. At that point , the Gravity fields have intersected and Gravity force is produced between the stone and the Earth. The same scenario occurs between a magnet and a magnetic mass.The only difference is that the Magnetic field is in a different configuration than the Gravitational field.Never the less both fields are Space phenomena.

Q: I have no background in quantum anything but I do know some Chemistry.How does an atom become magnetic?What has to occur in an atom for it to be magnetic?Can you make an atom magnetic through chemical bonds?Where can I start to learn this stuff? A link or recommended source would be nice.Thanks in advance.: Nope, but I got in school suspension on MY LAST DAY OF 8TH GRADE for wearing short shorts that werent even short. Stupid.

Q: Can steel be heat treated or otherwise changed from magnetically hard to magnetically soft?I want to use steel wool bits to visualize magnetic fields. The iron filings that you can buy for the purpose are junk - very irregular in shape and size. I have not found any source for high quality filings. I want long, thin particles, where long may be 1-2 mm and thin is 20% or so of the length. High aspect ratio is another way to put it. Particle length can certainly have a good degree of variability; I‘m more interested in the high aspect ratio.If you imagine small bits of 0000 steel wool, that‘s what I‘m looking for. But steel will retain a field once it has been exposed to a magnet. I want the particles to be magnetically soft so they don‘t retain the field. Is there any way to treat bits of steel wool to make it magnetically soft, or is there a source for high aspect ratio iron (not steel) bits?: They are unlimited you just have to move to diffrent areas on map

Q: physical significance of divergence of magnetic field in maxwells equation?: Divergence of Magnetic Flux Density 0 The above equation signifies the fact that the magnetic poles can not exist in isolated form. How. Take a simple example. consider a bar magnet. imagine a closed surface enclosing one of the poles. All the lines of magnetic flux which enter the closed surface inside the material of bar magnet will leave the region with in closed surface at areas outside the material of bar magnet. It means you never can enclose a magnetic pole inside a closed surface in such a way that there is only one directional (either inward or outward) flow of magnetic flux. But in case of electric charge. you can have isolated positive or negative charge. This is the significance that we have no isolated magnetic pole. a line of magnetic flux that leaves a bound region must return to that region.

Q: Mobile phone bracket magnetic effects on mobile phones?: Affect the magnet in the receiver so that you can't hear clearly,Some people say that the earth is a magnetic field, which is because the earth's magnetic field, magnetic force is too small, you use a 10 grams of NdFeB magnet to contact your mobile phone, your phone immediately scrapped

Q: Induction constant - the energy conversion gained from moving a magnetically charged object on a conductor type material like copper, silver, gold. I guess for every material has to be different. I searched around the net with no luck so I hope someone here might know what I‘m trying to explain.A percent (%) of energy gained or lost in the process. / Difference between the energy needed to run the process of electromagnetic induction and the energy gained from it.: To add to anonymous answer, the eddy currents are a function of the SHAPE of the material as well as the material itself. So in a transformer the core is made of laminations of thin material to minimize those currents. Ferrite uses powdered magnetic material to keep each piece small and reduce the eddy currents that way. So in effect there is no constant that can be applied. The only thing you should be aware of is that the better the conductor the more that energy can be lost in these effects. The second effect is called hysteresis. It takes energy to create a field in a magnetic material. When you reduce that field again you don't get all the energy back. Some has been lost to friction in the material and is turned to heat. Again the losses are dependent on factors such as the frequency of operation. Not a simple constant.

Q: What are the nano magnetic materials? What about carbon nanotube magnetic materials?: Although most people take a glass stirring method with ultrasonic stirring beat is dispersed, but the carbon nanotubes are truly highly dispersed, but also to be higher than the solid, is quite difficult, and not simply give some data to fix the.We can make it three:1., carbon nanotubes are highly dispersed by using jet nano industrialization technology, and the processing process does not destroy their tubular structure and is highly decentralized;2., according to different application requirements, 1:3-1:300 length diameter ratio can be controlled by cutting, and it also ensures that the material tubular structure is not damaged;3., in a short period of time, the quality of stable macro preparation;

Q: What is the use of magnetic materials?: The magnetic material can be used in electroacoustic, telecommunication, electric meter and motor, and can also be used as a memory element and a microwave element,

Q: Hi guys I would like to ask abt magnetic susceptibility. By definition it is an extent of magnetization of material. So higher value, the material more able to be magnetized?: See, magnetic permeability 1+ Xm , Xm magnetic susceptability For diamagnetic materials, Xm0 and for paramagnetic materials Xm0 and for ferromagnetic materials Xm0 and it has very high value So as Xm increases extent of magnetisation also increases.

Q: Can anyone explain interactions between magnetic fields?: there's a great distinction. Earth's magnetic field is created via its' northern and southern poles whilst its' gravity comes from it fairly is mass. Gravity and a Magnetic field additionally are 2 thoroughly diverse fields that act in thoroughly diverse techniques, an hassle-free occasion is that whilst gravity is often attracting an merchandise in the direction of Earths' middle, a magnetic field could repel an the two-can charge particle to the pole that this is attempting to realize. what's greater, the place Gravity enacts upon issues with a mass, a Magnetic field will in basic terms have an consequence on a magnet or charged particle.
