Magnetic properties of materials University of .

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 8×10 22 A m 2.
