A circular conductive loop of wire sits a centimeter away from a straight, infinitely-long current-carrying wire. For each of the following scenarios, predict the outcome and explain how you made this prediction.

(a)The loop sits stationary near the wire and does not move. The magnitude and direction of the current in the current-carrying wire does not change. Is there an induced magnetic field in the loop?

(b)The loop begins to move toward the infinitely-long current-carryingwire. Is there an induced magnetic field in the loop?

(c)The loop is again sitting stationary near the wire, and now it rotates in place. Is there an induced magnetic field in the loop?

pls thoroughly explain answers

Answer #1

According to the Faradays law of electromagnetic induction, when there is change in magnetic flux in the loop, induced emf is generated in it. This induced emf produces induced current in the coil, which generates induced magnetic field.

Simply, whenever there is change in magnetic flux across the loop, induced magnetic field is generated.
