The process of creating an electric current with a magnetic field.
What is Electromagnetic Induction?
100
The Variable that is changed in an experiment. It does not depend on any other variables.
What is an Independent Variable?
100
A magnet that is created by being connected to an electric current.
What is an electromagnet?
100
A machine that turns electrical energy into mechanical energy.
What is an Electric Motor?
100
A machine that converts mechanical energy into electrical energy.
What is an Electric Generator?
200
A pen used specifically to write on a tablet or device.
What is an example of electromagnetic induction?
200
The number of coils on the nail.
What is the Independent Va
riable in this situation?
200
Connect a source of power to a copper wire and then to a piece of metal like a nail. It will then become and electromagnet.
How do you make an electromagnet?
200
An Electric car. Powering its wheels which propels it forward.
What is an example of something that has an electric motor?
200
This machine is created by flipping the magnetic poles of a magnet inside a ring of coils which will then produce electricity.
How is an electric generator created?
300
By passing it through a magnetic field, or by moving the magnetic field past the conductor.
How can you create electromagnetic induction?
300
Size of the paperclips.
What is a control variable in an electromagnet?
300
If you increase the voltage of the battery, or you wrap the copper wire around your piece of metal more times, it will increase the magnetic force.
How can you increase the magnetism of an electromagnet.
300
This machine takes electricity and uses electromagnets and permanent magnets to form a magnetic circuit that turns electrical energy into mechanical energy.
How is an electric motor created?
300
Diesel, Gas, and Inverter.
What is an example of an electric generator?
400
Michael Faraday.
Who discovered electromagnetic induction?
400
The Variable that We are measuring in an experiment. It depends on the Independent Variable.
What is a Dependent Variable?
400
This device uses the change of direction of electric current. It uses electromagnetic Induction to create electricity waves coming from the device.
What is a wireless charger?
400

Would this be considered an electric motor?
400
No.
Would this be considered an electric generator?
500
Voltage produced do to a changing magnetic field.
How is a magnetic field related to Electromagnetic Induction?
500
The number of paperclips picked up.
What is the Dependent Variable in this situation?
500
MRI X-Ray machine.
What is an example of an electromagnet in the real world?
500
Use a stronger magnet.
How do you increase the power of an electric motor?
500
Flip the magnets poles faster.
How do you make a more powerful electric generator?
