(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A generator consists of a circular coil of radius 0.2 meters wrapped 10 times and is spun in a uniform magnetic field of 0.38 Tesla. It is connected (on the primary side) to a transformer with 7 turns on the primary side and 20 turns on the secondary side. If the secondary side is connected to a resistance of 8 ohms and a maximum current of 63 amps is required on the secondary side, at what angular speed should the coil be spun in the generator in rad/s?

2. Relevant equations

Vs =Ns/Np (Vp) or ξs =Ns/Np(ξp)

ξ= N B A w sin (wt), ξmax= N B A w

3. The attempt at a solution

What's the first step to solve this problem? Do I try to solve for the ξprimary which would also be equal to ξmax, since the maximum current is applied? Do I then use ξmax= N B A w to solve for w?
