☆ Magnetic Moment -- is the tendency of magnetic materials which allows them to be arranged in a magnetic field.

• It is denoted by m.
• Its unit is $\rm{}A \: {m}^{2}$ as it is product of Current & Area.

• It can be obtained by formula : $\rm{}m = \frac{ \tau}{B}$ , where m denotes magnetic moment, $\tau$ represent torque on dipole, and B is the magnetic field.
