For the first interval, the area is decreasing from its maximum to minimum value (relative to the perpendicular B field). Moreover, an interval follows such that the area that the flux is passing through is increasing from its minimum to maximum value.
Magnetic flux is the measure of the amount of magnetic field passing through a given area. It is represented by the symbol Φ.
The equation for magnetic flux is Φ = B x A x cos(θ), where B is the magnetic field strength, A is the area, and θ is the angle between the magnetic field and the surface.
To calculate magnetic flux, you need to know the magnetic field strength, the area, and the angle between the field and the surface. Simply plug these values into the equation Φ = B x A x cos(θ) to get the magnetic flux value.
Magnetic flux is used in a variety of applications, including electric motors, generators, transformers, and MRI machines. It is also used in the study of Earth's magnetic field and in the production of electricity through renewable energy sources like wind and hydro power.
Magnetic flux can have different effects on different materials. Some materials, called ferromagnetic materials, are strongly affected by magnetic flux and can become magnetized. Other materials, such as diamagnetic materials, are weakly affected and can become slightly repelled by magnetic fields.
