A. The magnitude of magnetic force:
The magnitude of magnetic field:
A long straight horizontal wire carries a current = 2.10 A to the left. A positive 1.00 C charge moves to the right at a distance 1.50 m above the wire at constant speed = 2000 m/s . (Figure 1)
A. What are the magnitude and the direction of the magnetic force on the charge?
B. Select the source(s) responsible for the magnetic field that exerts a force on the moving charge?
a) the charge
b) the current-carrying wire
c) the charge and the current-carrying wire
