Suppose that a rectangular toroid has windings and a self-inductance of 0.040 H. If the height for the toroid is 0.10 m, what is the current through it when the energy in its magnetic field is J?
A 10-H inductor carries a current of 20 A. How much ice at could be melted by the energy stored in the magnetic field of the inductor? (Hint: Use the value for ice.)
