Hi, i m new here n very poor in EE.. just want to ask that, is there any formula for us to calculate voltage induced on a coil if we have the info like the number of turns of the coil n the flux (mWb/sec).. cos i cant get from google as well...sorry for trouble n thanks for ur guiding...
This is Faraday's law of induction. V = -N (dΦ/dt) where Φ = B A (B is the magnetic field, and A is the area of 1 loop in the coil) For a fixed area A, this becomes V = - N A (dB/dt)
Hi adilee It is possible to get a dc voltage out of a coil, with the addition of an op-amp, a resistor and a capacitor. If the change in the field in the coil (by flipping it 180 degrees) is 2B, the coil area is A, and the number of turns is N, then the volt-seconds is 2 NAB. Put the voltage signal into an integrator circuit, as shown in the attached thumbnails at post #9 in thread https://www.physicsforums.com/showthread.php?t=352947 and get a dc voltage out. Bob S
