TL;DR Summary
What's the factor which induce EMF in case of falling magnet into the coil
If I drop the magnet into the electromagnetic coil, is magnetic flux density changed or cross sectional area changed during its falling? Actually I dropped a neodymium magnet into the coil and there was the voltage induced but I don't know what's the factor that induce the EMF in this case. Also if there is change of magnetic flux density or cross sectional area, how can I calculate those value without using experimental result I mean the induced EMF value.

1. How does the magnetic flux change during the falling of a magnet?

As a magnet falls towards a surface, the magnetic flux through a loop of wire near the magnet changes. This change in magnetic flux induces an electromotive force (emf) in the loop of wire, which in turn generates an electric current.

2. What factors affect the rate of change of magnetic flux during the falling of a magnet?

The rate of change of magnetic flux during the falling of a magnet is influenced by the strength of the magnet, the distance between the magnet and the surface, the orientation of the magnet, and the properties of the material through which the magnet is falling.

3. How is the induced emf related to the rate of change of magnetic flux during the falling of a magnet?

According to Faraday's law of electromagnetic induction, the induced emf in a loop of wire is directly proportional to the rate of change of magnetic flux through the loop. This means that a faster rate of change of magnetic flux results in a higher induced emf.

4. What is the direction of the induced current in the loop of wire during the falling of a magnet?

The direction of the induced current in the loop of wire is determined by Lenz's law, which states that the induced current creates a magnetic field that opposes the change in magnetic flux that produced it. This means that the direction of the induced current is such that it opposes the motion of the falling magnet.

5. How can the phenomenon of magnetic flux change during the falling of a magnet be utilized in practical applications?

The phenomenon of magnetic flux change during the falling of a magnet can be utilized in devices such as electromagnetic generators, where the induced current can be used to generate electricity. It can also be used in sensors and detectors to detect the presence of magnetic fields and changes in magnetic flux.
