In the given loop length of each side is `a`. Current flowing through the loop is `I=1` amp. Find its manetic dipole moment.

A current I is flowing through the loop , as shown in the figure . The magnetic field at centre O is

A copper wire of length 7 metre is bent to form a circular loop. If i current flows through the loop, find out the magnitude of magnetic moment of the loop.

Two identical pieces of metal wires are used to make a circular loop and a square loop same current is passed through both the loops what is the ratio of magneitc dipole moment associated with the circular loop that of the square loop ?

A circular loop and a square loop are formed from the same wire and the same current is passed through them . Find the ratio of their dipole moments.

A long straight wire is coplanar with a current carrying circular loop of radius R as shown in Fig. Current flowing through wire and the loop is I_0 and I, respectively. If distance between centre of loop and wire is r=2R, calculate force of attraction between the wire and the loop.

Find the magnetic moment of a thin round loop with current if the radius of the loop is equal to r and the magnetic induction at its centre is equal to X.

A square loop OABCO of side of side l carries a current i . It is placed as shown in figure. Find the magnetic moment of loop.
