Question
For a rotating loop of area A in a uniform magnetic field B, rotating with angular frequency ω, what is the induced EMF (ε) as derived on page 23?
Correct Answer
Option B is the correct answer.
Detailed Explanation
Page 23 states: 'ε = - dΦB / dt = BAω sin(ωt)'. The negative sign is for direction, but the magnitude is BAω sin(ωt).
Hint
Refer to the 'Rotating Loop - The Electricity Generator' section and find the derived formula for EMF.
