What causes an electric current in a wire a electric fields cause atoms to move in the wire b electron get the answers you need, now. Ferrimagnetic materials have high resistivity and have anisotropic properties the anisotropy is actually induced by an external applied field when this applied field aligns with the magnetic dipoles, it causes a net magnetic dipole moment and causes the magnetic dipoles to precess at a frequency controlled by the applied field, called.
These two metals, and alloys and mixtures containing them, are known as ferromagnetic materials because they concentrate magnetic lines of flux.
