Learn what magnetic flux is, how to calculate it, and how it relates to Faraday's law.

But what do we mean by magnetic, by magnetic flux? Well, like regular flux, we're still dealing with how things are kind of, you could say going through a surface.

Faraday's law, due to 19ᵗʰ century physicist Michael Faraday. This relates the rate of change of magnetic flux through a loop to the magnitude of the electro-motive force E ‍ induced in the loop. The …

Flux is a measure of the magnetic field's penetration of a particular area of space around a magnet, so of course if you move the magnet, it's field's penetration of that area of space will change.

Electric flux measures how much the electric field 'flows' through an area. The flow is imaginary & calculated as the product of field strength & area component perpendicular to the field.

When the magnetic flux through a conducting loop changes, current is induced in the loop. This current produces it's own magnetic field. Lenz's law tells us that the current flows in the direction that …

An emf induced by motion relative to a magnetic field is called a motional emf. This is represented by the equation emf = LvB, where L is length of the object moving at speed v relative to the strength of the …

Magnetic flux (ΦB) is the number of magnetic field lines (also called "magnetic flux density") passing through a closed surface (such as a conducting coil). The SI unit of magnetic flux is the weber (Wb) …

When it comes to inducing electromotive force (EMF), a change in magnetic flux is the key player. To achieve this, there has to be a shift in the number of magnetic field lines passing through a given area.
