Magnetic field of the solenoid can be represented by the voltage

    According to which law the magnetic field of the solenoid can be represented by the voltage induced in the search coil ? :rolleyes: :biggrin:

    Here's a formula that's use to find the field inside a current-carrying coil (should work for this too):

    [tex]B=\frac{\mu_{0}I}{2\pi{r}}[/tex]

    And as you probably know:

    [tex]I=\frac{V}{R}[/tex]

    Now just substitute (you do need to know the resistance inside the loop, though). I think this is what you are looking for.
