Question

Write an expression of magnetic flux density 'B' at a point in end-on position or an axial position of a magnetic dipole. (Derivation not required.)

Answer 1

Expression for magnetic flux density '$B$' in the end on position is given by $B=\frac{{\mu }_0}{4\lambda }\cdot \frac{2M}{r^3}$ where $M=$pole strength and $r=$ distance from the centre of the dipole.
