Two circular coils A and B are facing each other as shown in figure. The current i through A can be altered

Answer the following questions. You can make an electromagnet by wrapping coil around the nail and magnetise it by flowing a current through the coil. Can you use an aluminium nail instead of an iron nail? Why?

A ring of the radius R is placed in the y - z plane and it carries a current i. The conducting wires which are used to supply the current to the ring can be assumed to be vary long and are placed as shown in the figure. The magnitude of the magnetic field at the centre of the ring A is

There are two coils A and B separated by some distance. If a current of 4 A flows through A, a magnetic flux of 2 X 10^(-2) Wb passes through B (no current through B). If no current passes through A and a current of 2 A passes through B, what is the flux through A?

There are two coils A and B seperated by some distance. If a current of 2 A flows through A, a magnetic flux of 10^(-2) Wb passes through B (no current through B). If no current passes through A and a current 1 A passes through B, what is the flux through A?

Two coils A and B are separated by a certain distance. If a current of 4 A flows through A, a magnetic flux of 10^(-3)Wb passes through B (no current through B). If no current passes through A and a current of 2 A passes through B, then the flux through A is.
