Is there a calculation to work-out the products of simple magnet-coil induction?

[matthewgill]

Hello,

I need a calculation that can tell me how many Volts and Amperes a magnet passing through a coil will produce if you input the magnet strength, speed, number of coils, coil area etc...

Is there a common calculation I have missed for theoretically working this out? Or do you have to undergo experimentation?

If anybody knows a way of doing this, passing it on would be so very helpful.

Thank you

if you know the Inductance...

You manipulate this equation I would assume.

L=(N^2/l)(u/l)(A/l)

for your question. Yes, there is a well-known calculation for determining the products of simple magnet-coil induction. It is known as Faraday's law of induction and it states that the induced electromotive force (EMF) in a closed circuit is equal to the rate of change of magnetic flux through the circuit. This can be expressed mathematically as:

EMF = -N * (dΦ/dt)

Where EMF is the induced electromotive force, N is the number of turns in the coil, and (dΦ/dt) is the rate of change of magnetic flux through the coil.

To calculate the induced voltage, you would simply multiply the EMF by the number of turns in the coil. This can give you the voltage produced in the circuit.

To calculate the induced current, you would need to know the resistance of the circuit. Using Ohm's law (V=IR), you can calculate the current by dividing the voltage by the resistance.

In order to use this calculation, you would need to have some basic information about the strength of the magnet, the speed at which it is passing through the coil, and the area of the coil. You may need to do some experimentation to determine these values accurately.

I hope this helps to answer your question. Good luck with your research!
