Given the shape of a magnet and its magnetization, point by point, which force does it exert on itself, also point by point? We explain what 'force' means in such a context and how to define it by using the Virtual Power Principle. Mathematically speaking, this force is a vector-valued...
of items can be hung on it. A magnetic hook contains a powerful NdFeB permanent magnet that has a strong magnetic force and does not lose its magnetism easily. The magnet is covered by a steel shell and has one open face whereas the other one which is covered has a hook attached to ...

magnet′ic field′ n. 1. a region of space near a magnet, electric current, or moving charged particle in which a magnetic force acts on any other magnet, electric current, or moving charged particle. 2. a vector quantity defined by the force exerted on a given object at each point...
The second component arises due to alterations in the local magnetic field produced by magnetization of the ferromagnetic material, as the magnetic lines of force are concentrated in the metal hardware rather than B0. Thus, protons in the metal as well as in the adjoining tissues fail to preces...
