An elastic circular wire of length `l` carries a current `I`. It is placed in a uniform magnetic field `vecB` (Out of paper) such that its plane is perpendicular to the direction of `vecB`. The wire will experience

A conducting circular loop of radius r carries a constant current i. It is placed in a uniform magnetic field vecB such that vecB is perpendicular to the plane of the loop. What is the torque acting on the loop?

A straight wire of length 0.5 metre and carrying a current of 1.2 ampere is placed in a uniform magnetic field of induction 2 tesla. If the magnetic field is perpendicular to the length of the wire , the force acting on the wire is

A straight wire of length 1 m, and carrying a current of 1.8 A, is placed in a uniform magnetic field of induction 2T. If the magntic field is perpendicular to the length of the wire, then the force acting on the wire is

A straight wire of length 0.5 m carrying a current of 1.6 ampere is placed in a uniform magnetic field of induction 2 T. If the magnetic field is perendicular to the length of the wire, then force on the wire is

A loop of Irregular shape made of flexible conducting wire carrying clockwise current is placed in uniform inward magnetic field, such that its plane is perpendicular to the field. Then the loop

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
