A current -carrying loop of irregular shape is located in an external magnetic field. If the wire is flexible, why does it becomes circular?

A current carrying circular loop is located in a uniform external magnetic field. If the loop if free to turn, what is its orientation of stable equilibrium? Show that in this orientation, the flux of the total field (external field + field produced by the loop) is maximum.

A current carrying loop in a uniform magnetic field will experience

Assertion A flexeble wire loop of irregular shape carrying current when placed in a uniform external magnetic field acquires a circular shape. Reason For a given perimeter circular shape is having the greatert area.

A current loop of arbitrary shape lies in a uniform magnetic field B. show that the net magnetic force acting on the loop is zero.

The wire loop shown in figure carries a current as shown. The magnetic field at the centre O is ,

A circular flexible loop of wire of radius r carrying a current I is placed in a uniform magnetic field B . If B is doubled, then tension in the loop

A circular loop of radius a, carrying a current I, is placed in a tow dimensional magnetic field. The centre of the loop coincides with the centre of the filed The strenght of the magnetic field at the pariphery of the loop is B. find the magnetic force on the wire.

A circular loop carrying a current is replaced by an equivalent magnetic dipole. A point on the loop is in

A current carrying circular coil, suspended freely in a uniform external magnetic field orients to a position of stable equilibrium. In this state :
