2023年10月17日 · Magnetic Dipole Moment. Two magnetic poles having equal and opposite polarities separated by a small distance creates a magnetic dipole. A pair of two poles viz. North (N) and South (S) poles are referred to as magnetic dipoles and the moment generated by them is called the magnetic dipole moment or magnetic moment. It is generally represented ...
2016年8月19日 · The magnetic dipole moment of a substance (how well it acts as a magnet) can be determined by suspending a sample of the substance on a torsion fiber and measuring the period of the oscillations of the sample in an applied magnetic field. The larger the magnetic dipole moment, the faster the oscillation.
