Flux density in a coil?

  1. Dec 10, 2013 #1
    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?

    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 :)
