Electromagnetism: Magnetic Flux Density & Magnetic Flux

Magnetic Flux Density The symbol used is 'B' A measure of the strength of the magnetic field Sometimes called magnetic field strength It is a vector quantity The unit of magnetic flux density is the tesla (T) The direction of magnetic flux density is along the magnetic field lines from the north pole to the south pole of the magnet

Magnetic Flux The symbol used is Φ The amount of magnetic field in a given area It is a vector quantity Magnetic flux is measure with the unit weber (Wb) 1 Wb = 1 T m²

Φ = BA Φ = magnetic flux B = magnetic flux density A = area
