What does electromagnetic induction depend on?

Since the dielectric constant of a material medium determines the electric field in that medium, as most of us know, the region's net electric field will rely on the medium's characteristics.

Apart from that, Faraday's law provides the quantitative description of the electromagnetic induction phenomenon as follows:

The creation of the electric field is the cause of the emf.

According to Maxwell's equations, the phenomenon can be precisely described as,

Since we now know that a change in flux causes an electric field, it should be obvious that there are several ways to alter flux, including by adjusting the field's magnitude, area, or orientation with respect to the area.

According to the Lenz law and the law of conservation of energy, the negative sign denotes that the emf is produced in such a way that it tends to oppose changes in the field that produced it.

If a closed circuit experiences a flux change, the resulting emf will cause a current to flow through the circuit.

The emf and the electric field persist in the absence of a closed circuit.

Electromagnetic induction depends on the rate of change of magnetic flux through a closed loop.
