2020-3-31 Flux and flux density. To understand the meaning of magnetic flux (Φ) and magnetic flux density (B) think first about an ordinary bar magnet. Around the magnet there is a magnetic field and this gives a ‘flow of magnetic energy’ around the magnet. It is this flow of energy that we call magnetic flux (Φ).We think of magnetic flux as flowing from the north pole of a magnet round to its ...
