1. The magnetic field outside of the coil is said to equal zero, or near zero Tesla. Why is this so? What physically is happening to cause this?
2. Show, step-by-step, the derivation from equation (2) to equation (6).
3. Compare the range of the inductance of the coil found by equation to that of the inductance of the coil found by experiment. Are the two values for the inductance of the coil in agreement?
4. For each of the currents listed in table 2, and using the inductance of the coil found by experiment, determine the total stored energies in the coil.
