is it amplitude or frequency? if Any why ?can you tell me roughly how much electricity is produced in a thin wire oflength 1metre, amplitude 1cm and frequency 1000hz if it has high tension like in a steel wire ?Is there any equation relating these quantities

As I recall, the force exerted on a charge is the charge times the cross product of the velocity and magnetic field (Q times V cross B). So current would be related to the speed of the wire. The middle of the wire is moving 1 cm up and 1 cm down every 1/1000 second, so the speed is 2 cm per 1/1000 second or 2,000 cm per second, but that would be the peak speed. It would vary sinusoidally. The rest is left as an exercise for the reader. In other words, I don't know how to proceed from there.

The magnetic field of an infinitely lengthy immediately twine ought to correctly be received by employing employing Ampere's regulation. The expression for the magnetic field is B=consistent I/2 pi r the position consistent=mu 0 I is contemporary in amperes and r is the radial distance so as I in amperes will develop so does B in Tesla
