Understanding Flux Density in Coils: Equations and Factors Explained

[ElectricJosh]

Hello,

I am looking into magnetic flux density in coils can anyone tell me if there is a general equation that equates flux density to the electric current, the coil's dimensions and number of turns?

Any help would be appreciated.

Thanks.

Welcome to PF;
You should have that relationship in your notes already ...
Do you know how to find the magnetic field in a coil?
Do you now the relationship between flux density and magnetic field?

Thanks for your reply.

I typed in your questions in google and I found a website that explains the relationship quite well.

Well done - that site tells you about the magnetic field in a solenoid - if you know the relationship between magnetic field and magnetic flux density, you are set :)
