- 1. Multiple ChoiceElectromagnetism is whenmagnetism causes electricityelectricity causes magnetismelectricity and magnetism cancel each other outa strong magnet creates a permanent magnet
- 2. Multiple Choice
The voltmeter is at 0 in this image. How would you manipulate the experiment to create electricity (measured in volts)?Flip the magnet around so the North pole is facing outMove the magnet back and forthTake the magnet outAdd more coils around the paper cylinder - 3. Multiple ChoiceElectromagnetic induction is taking place in this experiment. How much electricity is being produced?-10 Volts10 Volts100 VoltsThis question cannot be answered based on this image
- 4. Multiple ChoiceHow could the experimenter increase the amount of electricity being induced by this experiment?Increase the number of coilsDecrease the number of coilsFlip the magnet aroundNothing, the amount of electricity cannot be increased
- 5. Multiple ChoiceHow would flipping the magnet in this experiment change the current?The current would not changeThe current would go to the rightThere would be no currentThe current would go CRAZY
- 6. Multiple ChoiceElectromagnetic induction is change in ___________________.surface areamagnetic polesmagnetic flux
- 7. Multiple ChoiceVoltage can be induced in a wire bya. moving the wire near a magnet.b. moving a magnet near the wire.c. changing the current in a nearby wire.d. all of these
- 8. Multiple ChoiceWhat would happen if I move a bar magnet in and out of a coil of copper wire?Electric current would disappearThe magnet would explodeElectric current will flow through the wireIt would produce a gravitational field
