Two identical coils are placed coaxially. They carry equal currents in same direction
NOTE in parts (a), (b) and (c) exclude the points at infinity.

Assertion Two infinitely long wires A and B carry unequal currents both in inward direction. Then, there is only point (excluding the ponts at infinity), where net magnetic field is zero. Reason That point lies between points A and B .

Two identical coaxial coils P and Q carrying equal amount of current in the same direction are brought nearer. The current in

Two identical coaxial circular coils are carrying current .i. each in the same direction. If the coils approach each other, then

Two circular, similar, coaxial loops carry equal currents in the same direction. If the loops are brought nearer, what will happen?
