Question

When is the magnetic field the strongest?

Answer 1

The force of magnetism coming from the magnet is called the "magnetic field", and is illustrated by lines. The magnetic field is strongest where the lines of force come together (and turn red), and is weakest when the lines of force are far apart (and turn blue).

Answer 2

This shows the field lines around a diskmagnet where the North pole is at the top. This shows the magnetic field strength around the disk magnetic. Again, it is strongest in the corners, not in the center of the poles! The magnetic field is weakest in the middle of its poles
