A circular coil, with radius of 10 cm, and 25 turns, rotates in a constant magnetic field of(adsbygoogle = window.adsbygoogle || []).push({});

strength 2.4 T, with the axis of rotation perpendicular to the direction of the magnetic

field.

If the coil rotates at a frequency of 50 Hz, what is the induced peak voltage?

Okay so I know the equation to use is:

emf=-Ndelta flux/delta t

I know all the variables in the equation except for time. I was wondering how you calculate the time. Is it just 1/50Hz?
