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 circular loop and a square loop are formed from two wires of same length and cross section. Same current is passed through them. Then the ratio of their dipole moments is

When current is passed through a circular wire prepared from a conducting material, the magnetic field produced at its centre is B. Now a loop having two turns is prepared from the same wire and the same current is passed through it. The magnetic field at its centre will be :

When current is passed through a circular wire prepared from a conducting material, the magnetic field produced at its centre is B. Now a loop having two turns is prepared from the same wire and the same current is passed through it. The magnetic field at its centre will be :

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 ?

Magnetic moment of a current carrying square loop be M . If it is converted in form of circle and same current is passed through it then find the new magnetic moment.

Magnetic moment of a current carrying square loop be M . If it is converted in form of circle and same current is passed through it then find the new magnetic moment.

Magnetic moment of a current carrying square loop be M . If it is converted in form of circle and same current is passed through it then find the new magnetic moment.

Two identical wires each of length L are bent to form a circular loop and a square loop. If the same current i flows in the two wires, then the ratio of the magnetic inductions at the centre of the circular and square loops is :

Two wires of equal lengths are bent in the form of two loops. One of the loops is square shaped whereas the other loop is circular. These are suspended in a uniform magnetic field and the same current is passed through them. Which loop will experience greater torque? Give reason.
