EMF frequency

  1. Jan 16, 2017 #1
    I got two series connected coils which I exited with 15 V AC. I got EMF between the space in the field and I measured it with gaussmeter saying 200 µT. I want to know the freqency of that generated electromagnetic field? Does any one know how to do it? Is there any Equation for it?

    Hi MIT. ##\quad## How about ##\ f_{\rm field} = f_{\rm AC\ source}\ ## ?

    The frequency which the B field changes its direction is the same frequency which the Voltage alternates. If you had a 60hz Vac, the B field would follow also this frequency.
