What is the formula for the magnetic field induction at any general point ‘p’
Magnetic induction at point ‘p’ due to magnet of moment
is ---(1) (Point lies on axial line)
Magnetic induction at point ‘p’ due to magnet of moment
is ------( 2 ) (Point lies on equatorial line)
These two Magnetic inductions are perpendicular to each other. The resultant Magnetic induction at p is given by
