Magnetic Force and Current Balance
Objective: In this lab, you investigate magnetic force between two parallel current-carrying wires and measure the fundamental constant μ0, the permeability in free space.
1. To use the measured d, we assume the current flows along the central axes of Rod CD and Rod AB. Because of the repulsive forces, the conduction electrons in each rod however tend to move as far away from the other rod as possible. Considering this effect, should the actual μ0 value be higher or lower than the measured μ0 value? Why?
2. If the length of Rod AB is doubled while the length of Rod CD remains the same, will the result change?
