Model

A solid body of horseshoe magnet consists of 3 parts and each part is defined.

This is because each part has its own magnetizing direction.

Results

The vectors of the magnetic field are shown below.

The magnetic field is directing from the north magnetic pole to the south magnetic pole.

 

The vectors of the magnetic flux density are shown below.

The magnetic flux are created as set in the direction tab.
