The back face of a circular loop of wire is found to be south magnetic pole. The direction of current in this face of the circular loop of wire will be :

The front face of a circular wire carrying current behaves like a north pole. The direction of current in this face of the circular wire is :

Near a circular loop of conducing wires as shown, an electron moves along a straight line. The direction of induced current if any, in the loop is

An electron moves along the line AB, which lies in the same lane as a circular loop of conducting wires. What will be the direction of the current induced in the loop, if any?

The diagram below shows a loop of wire carrying current I: What is the magnetic polarity of the loop that faces us?

A straight wire carrying a current is turned into a circular loop if the magnitude of magnetic moment associated with it is M then the length of the wire will be

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
