Magnetic Flux ± The magnetic flux associated with a magnetic field is defined in a way similar to electric flux ± Consider an area element d A on an arbitrarily shaped surface animation
Background image of page 4
Magnetic Flux ± The magnetic field in this element is B ± d A is a vector that is perpendicular to the surface ± d A has a magnitude equal to the area dA ± The magnetic flux Φ B is ± The unit of magnetic flux is T . m 2 = Wb ± Wb is a weber B d Φ= BA
