Im revising for my A levels and I could really do with a simple, straight forward definition for magnetic flux and magnetic flux density. Can anyone please help? I'd be very grateful.

Magnetic flux is a measure of the strength of a magnetic field passing through a given area. It is represented by the symbol Φ and is measured in units of Weber (Wb) or Tesla-meter squared (Tm²).
Magnetic flux density, also known as magnetic induction, is a measure of the strength of the magnetic field at a particular point in space. It is represented by the symbol B and is measured in units of Tesla (T).
Magnetic flux density is directly proportional to magnetic flux, with the constant of proportionality being the area through which the magnetic field passes. In other words, as the area increases, the magnetic flux density decreases, and vice versa.
Magnetic flux is a measure of the strength of a magnetic field, while electric flux is a measure of the strength of an electric field. While magnetic flux is represented by the symbol Φ, electric flux is represented by the symbol ΦE.
Magnetic flux can be measured using a device called a magnetic flux meter, while magnetic flux density can be measured using a device called a magnetometer. These devices use different methods, such as Hall effect or fluxgate magnetometry, to measure the strength of the magnetic field.
