Question

A vector quantity that measures the strength and orientation of a current loop as a magnetic source is called the:

Options

• magnetic dipole moment

• magnetic flux

• torque

• magnetic field intensity

Answer 1

The magnetic dipole moment is defined as the vector quantity that measures the strength and orientation of a current loop as a magnetic source. Its magnitude is \[m = NIA\], and the behaviour of a current loop in a field is identical to that of a magnetic dipole.
