Question

Where is the magnetic field strongest along the axis of a circular current loop?

पर्याय

• At the centre of the loop

• At a point one radius from the centre, but not at the centre

• Only at points infinitely far from the loop

• At every point equally along the axis

Answer 1

The field is strongest at the centre of the loop. It weakens as you move away from the centre in either direction along the axis.
