Magnetic Field outside AC Solenoid

  1. Mar 11, 2004 #1

    I have scoured the internet trying to find the right expression to calculate the magnetic field (B) outside of an AC driven solenoid. All i keep getting is stuff for DC driven or inside the solenoid.

    Can anyone help?

    Without looking up any references, what comes to mind is simply plugging in the time domain function of the current into any DC formula you have.

    For example.. the formula probably has a capital I in it.... change that to small i then find the time domain function for i


    i = 6sin377

    You'll end up with an answer that is also a trigonometric time varying function......
