What does the term 'Magnetic flux' refer to?

The term 'Magnetic flux' refers specifically to the total magnetic field passing through a given area. It quantifies how much magnetic field lines are penetrating a surface, and it is an important concept in electromagnetism. Magnetic flux is measured in webers (Wb) and is the product of the magnetic field strength and the area perpendicular to the field direction. This concept is critical for understanding how electromagnetic induction works, as changes in magnetic flux through a coil of wire can induce an electromotive force (EMF) due to Faraday's Law of Electromagnetic Induction. This definition aligns perfectly with the concept of magnetic flux, which emphasizes the relationship between the magnetic field and the area it influences.
