→ derive expression for magnetic field due to bar magnet at orbitrary point ?​

Answer 1

Answer:

Let O be the arbitrary point at a distance r from the center of the magnet. Magnetic field due to the magnet at point O has two components: Vertical component = Bv. Horizontal components = Bh.

from coulomb's laway magnetic field force, The force exerted by the N - Pole of strength 2m on unit pole at 'p' will be
