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.

The torque on the loop

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

Does the capacitance of a capacitor depend upon its shape?

A square current carrying loop is suspended in a uniform magnetic field acting perpendicular to the plane of the loop. If the force on one arm of the loop is vec(F) , the net force on the remaining three arms of the loop is

How does a current loop behave like a magnetic dipole?

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).

Current loop does not tend to rotate when its plane is bot to the direction of magnetic field. Why?
