Question

magnetic field on axis of circular current loop ...explain (3 mark question )​

Answer 1

Answer: We derived an expression for the magnetic field at the center of a circular current loop of radius R.

Each point on the axis is unique , because the magnetic field changes magnitude as we get further from the center of the loop , So there's no easy way to apply amphere's Law.

If the current in this loop and into the page at the bottom , in which direction is the net magnetic field on the axis of the loop at some point to the right ?

The net field on the axis point along the axis . In our case it points away from the loop , to the right
