100
A magnet, such as iron, that does not turn off.
What is a permanent magnet?
100
This happens when a north pole of one magnet approaches the south pole of another magnet.
What is attracts?
100
This is what a moving electric field in the form of a current creates.
What is a magnetic field?
100
This creates movement from electricity.
What is a motor?
100
This creates electricity from movement.
What is a generator?
200
This type of field
What is a magnetic field?
200
This happens when a north pole of one magnet approaches the north pole of another magnet.
What is repels?
200
This is what a moving magnetic field creates.
What is an electric field?
200
This device uses current to create a magnet.
What is an electromagnet?
200
These are the two basic parts of an electic motor.
What is an electromagnet and permanent magnet?
300
A magnet that uses electrical current running through a coil.
What is an electromagnet?
300
This is what happens to the magnetic domains of a magnetic material in the presence of an external magnetic field.
What is they align with the field?
300
This is made from electric and magnetic fields moving through space.
What is an electromagnetic wave?
300
This is how you strengthen a motor?
What is adding coils to the electromagnet or strengthening the current?
300
This is the opposite of an electric motor.
What is an electric generator?
400
This phenomena occurs when a material is able to maintain its magnetism after an external magnetic field is removed.
What is ferromagnetism?
400
These groups of atoms must be aligned for an overall magnet to exist.
What is magnetic domains?
400
A current moves straight out of the page. This is the direction of the created magnetic field.
What is counter-clockwise?
400
This device can increase or decrease the voltage by utilizing a different number of loops on either side of the device.
What is a transformer?
400
This is the name of the law that allows current to be induced in the presence of a changing magnetic field.
What is Faraday's law?
500
This type of phenomena occurs when a material does not maintain magnetism after an external magnetic field is removed
What is paramagentism?
500
At the most fundamental level, this causes a magnetic field to form.
What is a moving charge?
500
A current wraps around a solenoid left to right as depicted on the slide. This is the direction of the north pole.
What is to the left?
500
This is the type of current a transformer requires.
What is alternating current?
500
This is how one can increase the voltage induced in a generator.
What is increasing the change in magnetic field or increase the number of loops?
