Question 1 of 10 Electrical energy is transformed into mechanical energy in a motor when the electromagnet consistently turns in the same direction. What part of the motor causes this motion?

What is the primary difference between an electric motor and an electric generator? 1. Structurally they are similar but the elec- tric motor is more efficient than the electric generator. 2. Structurally they are similar but the elec- tric generator is more efficient than the elec- tric motor. 3. An electric motor is often much more complicated in structure than electric genera- tor. 4. An electric motor is used to produce elec- tricity while an electric generator is used to generate mechanic work with the input of electricity.

This picture describes an experiment that demonstrates induction. Select the three correctconclusions from these experiments below a) A current appears only if there is relative motion between the loop and the magnet (one must have moved relative to the other); the current disappears when the relative motion is stopped.b) Faster motion produces a smaller current.c) If moving the magnets north pole toward the loop causes a clockwise current, then moving the north pole away causes counterclockwise current; the results reverse when moving the south pole.d) Faster motion produces a larger current

Current flows through the two parallel wires in the directions shown in the image below. How will these two wires interact with one another? A) The wires will repel one another B) The wires will both move down C) The wires will attract one another D) The wires will both move up
