Introduction The name dipole is given to a bar magnet since the magnet has two poles, that is, South and North. In case a magnet is broken into two, creation of two isolated poles never exist because the individual fragment still contain two poles. Magnetic monopoles do not exist hence the simplest magnetic field source is the dipole. Baxis, magnetic field, for an ideal dipole is given by Baxis=µ04π=2µd3
