How to calculate the voltage of a coil?

+0
−2

Hi guys, I need to calculate the voltage that will center the magnetic field of a coil. The coil gonna be used in an induction heater thank you.

coil

Edit:
I edited the paragraph because it was misunderstood.

Edit2:

electromagnetic field electromagnetic field

We know that the higher the tension (voltage), the wider the magnetic field, and the higher the current the stronger thos magnetic fields became.

So if the voltage increases the magnetic fields will eventually align in the center isn't?

The magnetic field will always be strongest in the middle of the solenoid. It will be slightly less at the ends of the solenoid and, it will be a lower value on the outside of the coil half way between the ends of the solenoid.

In other words, no amount of voltage present on the coil will change what I have said above and there will be no magical realignment of the magnetic field shape.

This is not possible since the voltage has no effect on the position or shape of the magnetic field. The position and shape are fixed by the position and shape of the coil.

But the higher the tension, the wider the magnetic field

No, as I already explained. This is assuming you mean "EMF" or "voltage" when you say "tension".

the higher the current the stronger thos magnetic fields became

Yes, but all parts of the field scale proportionally with the current. The shape of the magnetic field caused by the coil remains the same.

I suppose what you are asking is: "How to increase the strength of the magnetic field in a solenoid?"

This can be done by increasing the number of turns of the solenoid as well as by increasing the current through these coils.
