Positive energy Positive volts An induced current A negative current
Use more turns of wire, a bigger magnet and move the magnet faster Use more turns of wire, a stronger magnet and move the magnet faster Use less turns of thinner wire, a stronger magnet and move the magnet slower Use the same number of turns of wire, a bigger magnet and move the magnet slower
Generates useful kinetic energy Generates gravitational potential energy Transfers electrical energy into kinetic energy Transfers kinetic energy into electrical energy
Is positive only Is negative only Has a bigger voltage and a bigger frequency Has a bigger amplitude and a lower frequency
The wire produces alternating current The wire produces direct current The wire produces no current The wire produces direct frequency
Always works using direct current Always produces direct current Always works using alternating current Always decreases the voltage
Makes direct current like a battery Decreases the current Decreases the power Increases the current
