magnetic flux density

Magnetic flux density, also known as magnetic induction, is a vector quantity symbolized by B. It represents the total magnetic field within a material, encompassing contributions from external currents and the material's intrinsic magnetic properties. Magnetic flux density is measured in units of tesla (T).123

Magnetic fields, which exert magnetic forces, can be visualized using lines of magnetic flux. The density of these lines indicates the strength of the magnetic field; where the field is strong, the lines are crowded, and where it is weak, they are spread out. These field lines form continuous closed loops, emerging from north poles and entering south poles. Unlike electric fields, magnetic field lines do not begin or end on charges, as no magnetic monopoles have been discovered.13
