Question 1
What does Ampère’s Law relate in a closed loop around a current-carrying conductor?
Question 2
Which equation is the standard form of Ampère’s Law for steady currents?
Question 3
For a long straight wire carrying current, what is the shape of the magnetic field lines around the wire?
Question 4
A circular Amperian loop encloses no current. What is the value of $\oint \mathbf{B} \cdot d\mathbf{l}$ for that loop in the steady-current case?
Question 5
Why is Ampère’s Law especially useful for highly symmetric current distributions?
