Classifications of Magnetic Materials by Ron Kurtus

These materials when placed in a magnetic field becomes weakly magnetized in the direction opposite to that of the applied field There is no permanent dipole moment in each atom The induced magnetic moment produced in these materials during the application of the external magnetic field decreases the magnetic induction present in the specimen

Magnetic properties of materials

Magnetic moment is a vector quantity which has both direction and magnitude This is important because although the atoms in most materials may have magnetic moments they are not easily brought into alignment in one direction so the moments cancel each other leading to weak magnetization The Earth has a magnetic moment of 810 22 A m 2
