Question

what is the direction of induced current in a square loop moving away from a straight current carrying conductor the side of the square being parallel to the conductor?

Answer 1

There are three ways of inducing current in a loop/coil of wire as shown in my book. We can have a magnet approach a coil of wire, or a wire approaching a magnet. Both can be understood in the same way

On the other hand, we can also change the magnetic flux by pushing a loop of wire into a magnetic field.

This confuses me. Two vertical lines are cutting across the field. But since they are connected, the induced current, I conjecture, would cancel each other.

I saw in a YouTube video that to determine the direction in such situations as 2, one curl the fingers of their right hand along the wire, with the thumb pointing in the direction of the field. So the curled fingers are in the direction of the current. Basically the directions of current indicated by the thumb is always opposite the direction of the changing field.

Answer 2

hey mate
here's the solution
