Magnetic Forces
When a north pole of a magnet is placed next to the south pole of another magnet.
They will attract
The movement of electric charges (electrons) through a conductor.
What is electricity?
a magnet run by electricity that can be turned on and off
What is an electromagnet?
An area around which an object feels a non-contact force.
What is a "field"?
A push or a pull.
What is a "force"?
Iron, nickel or cobalt
What is "magnetic material"?
Electric charges are transferred, and not created or destroyed
What is "conservation of charge"?
What is a "solenoid"?
What happens to the force of a magnetic field when you get farther from the magnet.
What is "get weaker"?
This is an example of electrical energy found in nature.
What is "lightning"?
Happens to the magnetic force when a magnet gets closer to another magnetic material.
What is "get stronger"?
The reason a balloon sticks to the ceiling when it gets rubbed against a piece of wool.
What is "become negatively charged"?
Created when a magnet is moved inside a coil of wire.
What is electricity?
These numerous small objects can show the field lines around a magnet.
What are "iron filings"?
The opposite of attract
What is repel?
Occurs to the electric force when there is a bigger imbalance between the positive and negative charges.
What is "get stronger"?
Wrap more coils of wire around a magnetic material or increase the electrical current through the wire with more batteries.
What is "make an electromagnet stronger"?
The movement of electric charges through a circuit.
What is "current"?
When a north pole of a magnet is placed next to the north pole of another magnet.
What is repel?
This has a negative electric charge.
What is electrons?
When you move a magnet through a coil of wire.
What is "induce and electric current"?
What are "non-contact forces"?
