Question

why magnet has more strength at pole than middle​

Answer 1

• In a solenoid, the field lines within are relatively constant and parallel, and so, the magnetic field is strongest as compared to the poles, at which the field lines diverge.

Answer 2

Explanation:

=> For a magnet, the flux lines repel each other so the field will be weaker at the sides. But they are concentrated at the poles, where they originate, so the field is stronger. ... So, poles have more force than the middle portion
