Q: Is the refrigerator strip sealed with magnetic material?: Not magnetic materials, some silicone, and some resin, but some brands joined the magnetic particle, so there is adsorption.

Q: what features of atomic structure determine whether an element is diamagnetic or paramagnetic?: In most atoms, electrons occur in pairs. Electrons in a pair spin in opposite directions. So, when electrons are paired together, their opposite spins cause their magnetic fields to cancel each other. Therefore, no net magnetic field exists. Alternately, materials with some unpaired electrons will have a net magnetic field and will react more to an external field. So most materials can be classified as diamagnetic, paramagnetic or .ferromagnetic.

Q: The problem is as follows: There is a point magnetic dipole embedded at the center of a sphere (radius R) of linear magnetic material of permeability μ. What is the magnetic field inside the sphere?I know that this problem has been solved in many books.But I am trying a different method. Since the magnetic field of a magnetic dipole takes the same form as electric field of an electric dipole, I calculated the electric field inside a sphere (of linear dielectric material of permittivity ε) having a point electric dipole embedded at the center.And then just replaced ε by 1/μ and the electric dipole moment ‘p‘ by the magnetic dipole moment ‘m‘ and of course epsilon naught by one over mu naught. But the answer does not match the correct answer.Is this method of mine wrong?: The magnetic dipole will magnetize the sphere. This magnetization will create a field of its own. We need to find the net field, that is the resultant field due the dipole and the magnetization of the sphere. My answer is almost the same as that given in Griffiths text except that in the denominator of the second term mu naught and μ are interchanged in my answer

Q: For example, at school you may have performed an experiment designed to prove the existence of a magnetic field. It may go like this: Sprinkle iron filings on a sheet of paper. Then place the sheet over the magnet. When the sheet is vibrated, as if by magic the iron p. 27filings bunch up near the magnet’s poles and form into the pattern of the magnetic field. If you did that, could you actually see the magnetic field? No, but its effect on the iron filings is plain to see, giving you convincing proof that magnetism exists.: magnetism is the same force as electricity.its still simply the principle that opposite charges attract, but when force is defined in terms of relativity you get magnetism. Newtonian (simplified) force: fma (m mass, aacceleration) Relativity (correct) force: fma/sqrt(1-v^2/c^2) (vvelocity, cspeed of light in a vacuum) combined with the velocity of spinning electrons you can get tremendous scaling of the electrical force which allow it act at a further distance than could be explained in Newtonian physics. in general a field is simply a mapping of a unique vector on every point on a space.in this case it is an acceleration vector, and the source is some magnetic force. So a field is simply an abstraction used to facilitate calculations, and requires no explanation.I took the liberty of assuming you meant to ask what the magnetic force comes from

Q: What are the nano magnetic materials? What about carbon nanotube magnetic materials?: The magnetic material should be mainly made of nano ferrite. Carbon nanotubes become good electromagnetic shielding materials because of their excellent electrical conductivity, but they are not magnetic in themselves.

Q: What materials will block or inhibit a magnetic field?: as above. also, there is no iron in a usb drive. that would be be like wondering why a crab hasnt evolved into a moon yet.

Q: you see how paperclips have magnetic domains, and when a magnet is place near it becomes a temporary magnets. Does plastic or rubber have domains two like metal or paperclips?: No not ordinary rubber or plastic. If you incorporate iron or other magnetic material in the plastic or rubber, then you can make the material interact with magnets

Q: What is the use of magnetic materials?: Magnetic tapes for recording language, music, image information, magnetic storage devices for computers, vouchers for passenger travel, magnetic cards for fare settlement, etc..

Q: How to increase magnet magnetism?: First of all, the magnet is a ferromagnetic substance. If you want it to be magnetic, you must magnetize it and let the magnetism disappear. Magnetization is the process by which a magnetic substance is not magnetic. The principle of magnetic material is divided into many small areas, each tiny area is called a magnetic domain, each magnetic domain has its own magnetic distance (that is, a small magnetic field). Generally, the magnetic distances of each domain are different, and the magnetic fields cancel each other, so the whole material is not magnetic. When the direction of each domain is uniform, the whole material shows magnetism. The so-called magnetization is to make the magnetic domain of the magnetic domain in the magnetic material become consistent. When the material that does not exhibit magnetism is placed into another strong magnetic field, it is magnetized, but not all materials can be magnetized, and only a few metals and metal compounds can be magnetized. On the contrary, when the degaussing magnetized material, influence of external energy, such as heat, impact, the domain which the magnetic moment direction will become inconsistent, magnetism will be weakened or disappeared, this process is called degaussing. Magnetism, usually referred to as ferromagnetism, is the magnetism of a magnet. In addition to metal, iron also includes metals, nickel, cobalt, some rare earth metals, and certain oxides and compounds of these metals. The physical and magnetic paramagnetic, anti magnetic, anti ferromagnetic, paramagnetic and diamagnetic materials in nature are, so the magnet becomes very strange.

Q: How work magnet?: To put it into super simple words: You know that a magnet attracts a metal. The magnetic field is the area around a magnet where it has an effect on metals.
