Question

A student used a vernier magnetic field sensor to measure the strength of the magnetic field generated by a bar magnet. at which position is the
strength of the magnetic field strongest point a or point b?

Answer 1

The position is the strength of the magnetic field strongest is is the place where the magnetic field leaves, being point A.

What generates a magnetic field?

When an electrically charged particle moves, it creates a magnetic field. According to the laws of electromagnetism, this magnetic field originates from the variation of the electric field strength.

In the region of the poles we see that the lines of magnetic induction are closer to each other, therefore, we consider that close to the poles the magnetic field is more intense.
