the magnitude of the voltage induced in a conductor moving through a stationary magnetic field depends on the ------- and the------- of the conductor. A)lenght, speed. B)distance, circumference. C)resistance, current. D)color, capacitance.

length and speed...you are cutting lines of magnetic force, so to get the most per unit times, you need length, and fast.

length and speed

Thank-you for the answer because I do not understand electricity.I am 51 trying to get my diploma.
