Question

What is a magnetic axis?

Answer 1

1. Definition: The straight line joining the two poles of a magnet (as the magnetic poles of the earth) is known as the magnetic axis.
2. The axis joins the poles of a magnetized body, specifically that joining the earth’s magnetic poles.
3. It is also the center line of the bar magnet that crosses both the poles with the applied torque.

Therefore, the magnetic axis is defined as the line which joins the two poles of a magnet.
