  1. Two coils have mutual inductance M if a changing current in coil 1 induces an EMF in coil 2. The relationship is:
  2. The energy density u (energy per unit volume) in a magnetic field B is:
  3. The magnetic field in a region has magnitude 0.80 T. Calculate the energy density (in J/m³) in this region. (Use mu_0 = 4pi times 10^-7 T·m/A)
  4. Electromagnetic induction is used in all of the following EXCEPT:
