The unit of magnetic moment is

The current associated with an electron of charge $e$ moving in a circular orbit of radius $r$ with speed $v$ around the positively charged nucleus is given by

$A$ current carrying wire of length $L$ is transformed into a coil of $N$ turns. To achieve maximum magnetic moment,the coil

$A$ current loop placed in a magnetic field behaves like a

$A$ wire of length $2 \, m$ carrying a current of $1 \, A$ is bent to form a circle. The magnetic moment of the coil is

Magnetic induction produced at the centre of a circular loop of radius $R$ carrying a current is $B$. The magnetic moment of the loop is $(\mu_0 = \text{permeability of free space})$
