The magnetic field at the centre of the circular loop as shown in Fig. when a single wire is bent to form a circular loop and also extends to form straight sections is

Find the magnetic field at the centre of the circular loop shown in figure.

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

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

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

B_0 is the magnetic field at point P fir s given straight wire as shown in figure. If this wire is bent into a circular loop,then magnetic field at the center of the loop is

B_0 is the magnetic field at point P for a given straight wire as shown in figure. If this wirre is bent into a circular loop, then magnetic field at the centre of loop is

A wire of length 'I' is bent into a circular loop of radius R and carries a current I. The magnetic field at the centre of the loop is 'B '. The same wire is now bent into a double loop. If both loops carry the same current I and it is in the same direction, the magnetic field at the centre of the double loop will be

What will be magnetic field at centre of current carrying circular loop of radius R?

The resistance of three parts of a circular loop is shown in the figure. The magnetic field at the centre 0 is

A long wire carries a steady curent . It is bent into a circle of one turn and the magnetic field at the centre of the coil is B . It is then bent into a circular loop of n turns. The magnetic field at the centre of the coil will be
