What are the effects of relative motion between a conductor and a magnetic field?
How can the power output of electrical generators be increased?
How did the discovery of electromagnetic induction effect industrialization?
How is the efficiency of electricity generation dependent on the source of energy?
Faraday’s law of induction includes a rate of change. Which other areas of physics relate to rates of change? (NOS)
magnetic flux Φ as given by Φ = BA cos θ
that a time-changing magnetic flux induces an emf ε as given by Faraday’s law of induction ε = − N ΔΦ/Δt
that a uniform magnetic field induces an emf in a straight conductor moving perpendicularly to it as given by ε = BvL
that the direction of induced emf is determined by Lenz’s law and is a consequence of energy conservation
that a uniform magnetic field induces a sinusoidal varying emf in a coil rotating within it
the effect on induced emf caused by changing the frequency of rotation
