How to induce current on a static conducting material?

[Jay_zero]

Dear Physicists,

I am currently thinking of a way of inducing a current in a conducting material by a magnetic field. I am not good at magnetism and electricity at all, but I think it should look like the picture below. By the way, the material in the middle does not move.

Does anyone think that this setup will help induce a current in the material? if not how should I do it. By the way, is it possible to change the strength of the magnets at all? Please guide me in the correct direction as I am very lost here and don't know where to look. Suggestions are much appreciated on what field to look at. Thank you everyone.

You need a change in magnetic flux to induce current . So you will have to move those magnets some how . What is your purpose for inducing current .

It is not used to power up anything electrical at all. However, I think it is silly to say that I don't even know if I really need a current in the material at all. Anyway, so I need to move the magnets? like left to right and back again? Do I have to move both magnets or one magnet? However, are there any equations to calculate how much magnetic strength I need for a given distance? And last question, how to create a magnetic field with variable strength?

Thanks again.

Watch the first 20 minutes of this video and he talks about electromagnetic induction and it might help you and it is a very good video.

Or you can move the conductor through the B field to induce current , Maybe you could have it rotating or something.
And if you have it rotating and you know the angular frequency, And you know the field strength , then you can calculate the magnetic flux as a function of time .
Using Flux=Acos(bt) where a is the cross-sectional area and b is the angular frequency
and the time derivative of this will be voltage .

Dear fellow scientist,

The setup you have proposed is indeed a possible way to induce a current in a conducting material using a magnetic field. This is known as electromagnetic induction, where a changing magnetic field can create an electric current in a conductor.

To improve the effectiveness of this setup, you could try using stronger magnets or increasing the number of turns in the coil around the conducting material. Additionally, you could also try varying the speed at which the magnets move or changing the orientation of the magnets relative to the conducting material.

Another approach to inducing a current in a conducting material is by using a changing electric field instead of a magnetic field. This is known as capacitive coupling, where a changing electric field can create a current in a nearby conductor. This can be achieved by using a varying voltage source connected to the conducting material.

I highly recommend researching more about electromagnetic induction and capacitive coupling to gain a better understanding of these concepts and how they can be applied in your experiment. Good luck with your research!

Sincerely,
