One of the two identical conducting wires of length L is bent in the form of a circular loop and the other one into a circular coil of N identical turns. If the same current passed in both, the ratio of the magnetic field at the central of the loop (B_(L)) to that at the central of the coil (B_(C)) , i.e. (B_(L))/(B_(C)) will be :

A long wire is first bent into a circular coil of one turn and then into a circular coil of smaller radius, having n identical turns. If the same current passes in both the cases, find the ratio of the magnetric fields produced at the centre in the two cases.

A uniform wire is bent into one turn circular loop and same wire is again bent in two circular loop. For the same current passed in both the cases compare the magnetic field induction at their centres.

A wire of length L is bent to form a circular loop of number of turns n. The coil is placed in a magnetic field of induction B and a current is passed through the coil. What will be the maximum torque acting on the coil?

A steady current flows in a long wire. It is bent into a circular lopp of one turn and the magnetic field at the centre of the coil is B. If the same wire is bent into a circular loop of n turns, the magnetic field at the centre of the coil is
