Question 2: Electromagnetic Induction

Question

A system $$S$$ consists of two coils $$A$$ and $$B$$. The coil $$A$$ carries a steady current $$I$$. While the coil $$B$$ is suspended nearby as shown in figure. Now, if the system is heated, so as to raise the temperature of two coils steadily, then

Accepted Answer

Coil A carries a steady current with increase
in temperature, its resistance increases and so
current is decreasing at a constant rate, this
induces an emf in B which opposes this change
i.e., current in coil B is in same direction of A,
therefore they attract to each other.

Answer

the two coils shows attraction

Answer

the two coils shows repulsion

Answer

there is no change in the position of the two coils

Answer

induced current are not possible in coil $$B$$
