Magnetic flux density is a vector field which we identify using the symbol B and which has SI units of tesla (T). Before offering a formal definition, it is useful to consider the broader concept of...Magnetic flux density is a vector field which we identify using the symbol B and which has SI units of tesla (T). Before offering a formal definition, it is useful to consider the broader concept of the magnetic field. Magnetic fields are an intrinsic property of some materials, most notably permanent magnets.
