Magnetic Moment (Noun)
Meaning
The torque exerted on a magnet or dipole when it is placed in a magnetic field.
Classification
Nouns denoting natural phenomena.
Examples
- The magnetic moment of a magnet is a measure of the strength and orientation of its poles in a magnetic field.
- The torque exerted on a magnet is directly proportional to its magnetic moment and the strength of the external magnetic field.
- In the presence of an external magnetic field, the magnetic moment of a dipole will align itself either parallel or antiparallel to the field lines.
- The magnetic moment of a bar magnet is determined by the pole strength, the distance between the poles, and the magnet's orientation in the magnetic field.
- The magnetic moment of a charge carrier, such as an electron, can be described in terms of its orbital and spin angular momenta.
