Magnetic Dipole

Magnetic Dipole Magnetic Dipole : – Just as two charges of equal magnitude but opposite nature form an electric dipole, in the same way two magnetic poles of equal pole strength (m) located at a certain distance (effective length) form a magnetic dipole. Examples of magnetic dipole :- Bar magnet/current carrying loop/current carrying solenoid…
