1. State the right-hand rule for the magnetic field lines from a current-carrying wire.

2. You’ve got magnetic field lines making circles around a current-carrying wire. How do you find the magnetic field vectors?

3. How do you find the direction of the magnetic field at the center of a current-carrying loop of wire?

4. In Ampere’s law, how do you determine the sign of currents for calculating Iencl?
