The magnetic field at the centre of circular loop in the circuit shown below is

The magnetic field at the centre of circular loop in the circuit shown below is

On meter length of wires carriers a constant current. The wire is bent to from a circular loop. The magnetic field at the centre of this loop is B . The same is now bent to form a circular loop of smaller radius to have four turns in the loop. The magnetic field at the centre of this loop B . The same is now bent to form a circular loop of smaller radius of have four turns in the loop. The magnetic field at the centre of this new loop is

Magnetic field at the centre ofa circular loop of area A is B. Then magnetic moment of the loop will:

The magnetic field at O due to current in the infinite wire forming a loop as a shown in Fig.
