Does the torque acting on a loop carrying current in a magnetic field depend upon the shape of the loop.

The torque on the loop

Find an expression for the torque acting on a current carrying loop suspended in a uniform magnetic field. Under what conditions this torque will be maximum and minimum ?

The torque on a planar current loop depends upon its ara and is indpeendent of the shape of the loop of the palanar loop. Explain.

A rectangular loop of wire of size 4 cm xx 10 cm carries a steady current of 2A. A straight long wire carrying 5A current is kept near the loop 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(fig).

Can a magnetic field line from a closed loop? Explain.
