Question
A current I is passed through a wire. A second wire of length L is moving
perpendicular to the magnetic field generated by the first wire (see sketch below)
with velocity v at a distance d. Consider the magnetic field B to be constant over
the range of motion of the second wire (i.e. d » 1). You need to calculate the
potential generated between the ends of the second wire. Please select
statements that would describe your approach to solving the problem.

☐ a. Use the expression for the magnetic force between two current-carrying
wires.
☐ b. Use the expression for the magnetic field of a current-carrying wire.
О с.
Use an expression for the electromotive force (EMF) induced by the
magnetic field.
