A 0.35 m2 coil with 50 turns produces a maximum emf of 45 volts in a magnetic field of 0.4 Tesla. What is the speed of rotation of the coil?

Can you show the steps too so I can understand? Thanks

  • Physics -

    ε=dÔ/dt = d(NBAcosωt)/dt =
    = - NBAω sinωt,
    ε(max) = NBAω =>
    ω=ε(max)/ NBA =45/50•0.4•0.35 =6.43 rad/s
