'Permanent' magnets get their magnetism from unpaired electrons. There are two sources of this magnetism. Orbital motion of the electrons and also from the spin of the electrons. Paired electrons cancel out each others magnetism. read more
‘Permanent’ magnets get their magnetism from unpaired electrons. There are two sources of this magnetism. Orbital motion of the electrons and also from the spin of the electrons. Paired electrons cancel out each others magnetism. The only elements that are ‘permanent’ magnets are iron, nickle and cobalt. read more
The magnetic state (or magnetic phase) of a material depends on temperature and other variables such as pressure and the applied magnetic field. A material may exhibit more than one form of magnetism as these variables change. read more
Magnetism is one aspect of the combined electromagnetic force. It refers to physical phenomena arising from the force caused by magnets, objects that produce fields that attract or repel other objects. A magnetic field exerts a force on particles in the field due to the Lorentz force, according to Georgia State University's HyperPhysics website. read more
