Question: What is the formula for the induced electromotive force (emf) in a coil when the magnetic flux changes?

Options:

  1. emf = -dΦ/dt
  2. emf = F/q
  3. emf = W/t
  4. emf = mv^2/r

Correct Answer: emf = -dΦ/dt

Solution: 

The induced emf in a coil is given by Faraday\'s law of electromagnetic induction, which states that emf = -dΦ/dt, where Φ is the magnetic flux.
