is a form of magnetism whereby certain materials are attracted by an externally applied magnetic field, and form internal, induced magnetic fields in the direction of the applied magnetic field. In contrast with this behavior, diamagnetic materials are repelled by magnetic fields and form induced magnetic fields in the direction opposite to that of the applied magnetic field.[1] Paramagnetic materials include most chemical elements and some compounds;[2] they have a relative magnetic permeability greater than or equal to 1 (i.e., a non-negative magnetic susceptibility) and hence are attracted to magnetic fields
