Question

What is menetic field intensity ? Derive
the expression for magnetic
potential due to bar magnet.
.​

Answer 1

Answer:

Magnetic moment of magnetic dipole m = qm 2l, its direction is from S to N. Consider a point P on the axis of magnetic dipole at a distance r from mid-point O of dipole. but opposite to each other and B1>B2. This is expression for magnetic field intensity at axial position due to a short bar magnet.

Answer 2

Answer:

vector quantity pertaining to the condition at any point under magnetic influence (as of a magnet, an electric current, or an electromagnetic wave) measured by the force exerted in a vacuum upon a free unit north pole placed at the point in question. — called also magnetic force.

Magnetic Potential at Any Point Due to a Short Bar Magnet:

It is denoted by 'V' and its S.I. ... Consider a point 'P' near the dipole at distance 'r' from its centre O. i.e. OP = r. Let 'θ' be the angle between the line joining the point from the centre O and the axis of the dipole (angle between OP and SN).
