A circular coil of wire carries a current . `PQ` is a part of very long wire carrying a current and passing close to the circular coil. If the direction of currents are those shown in figure, then the direction of the force acting on `PQ` is

A circular coil carrying current behaves as a

The front face of a circular wire carrying current behaves like a north pole. The direction of current in this face of the circular wire is :

In the figure PQ is a long current carrying wire which is placed near a current carrying coil. The direction of the force acting on PQ will be

In the figure PQ is a long current carrying wire which is placed near a current carrying coil. The direction of the force acting on PQ will be

Three long straight wires A , B and C are carrying currents as shown in figure. Then the resultant force on B is directed

A charge Q moves in Y-direction in the plane of a very long wire carrying a current l as shown in figure . Instantaneous force on the charge is

A rectangular loop of wire of size 4 cm xx 10 cm carries a steady current of 2A. A straight long wire carrying 5 A current is kept near the loop as shown. If the loop and the wire are coplanar, find (i) the torque acting on the loop and (ii) the magnitude and direction of the force on the loop due to the current carrying wire.

A rectangular loop of wire of size 2 cm xx 5cm carries a steady current of 1A. A straight long wire carrying 4 A current is kept near the loop as shown. If the loop and the wire are coplanar, find (i) the torque acting on the end (ii) the magnitude and direction of the force on the loop due to the current carrying wire.
