Magnetic flux
Magnetic flux is a measurement of the total magnetic field which passes through a given area. It is a useful tool for helping describe the effects of the magnetic force on something occupying a given area.
Magnetic flux is the product of the average magnetic field times the perpendicular area that it crosses.
Magnetic flux = Magnetic field * Area * (angle between the planar area and the magnetic flux)
The equation is:
Φ = B A cos(θ)
Where:
Φ: Magnetic Flux
A: Area
B: Magnetic field
θ: angle between a perpendicular vector to the area and the magnetic field
