WebWe talked about diamagnetism in an earlier video and we used current in a loop of wire as an analogy. So if current is moving in this direction in a loop of wire, so I represents current, a magnetic field is created. And at the very center of this loop, the magnetic field is … Web1.2.1 Diamagnetism. In most diamagnetic materials, atoms have an even number of electrons in the partially filled shells, so that the major magnetic moments are due to electron motion in orbits, the spin magnetic moments (one in up-spin and one in down-spin) tend to cancel each other. ga as is formParamagnetism is a form of magnetism whereby some materials are weakly 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. Paramagnetic materials include most chemical elements and some compounds; t… gaas indirect band gap
