Magnets and Magnetism
The ends of the magnet where the magnetic field is the strongest
What are magnetic poles
What do you call coil that has an iron core and that acts as a magnet when an electric current is in the coil?
What is an electromagnet?
The space around a charged object where another charged object can experience an electric force
What is an electric field
Gravitational Force is (stronger/weaker) between objects that have small masses.
Pick one!
weaker
What are magnets usually made of?
iron or magnetite
This form of electromagnetic transportation from your textbook glides on magnets to move
What is a maglev train?

Answers will vary
How is Earth like a magnet?
Earth has a magnetic field. and a north and south pole
A force of attraction between objects due to their mass
GRAVITY
Name all three types of charging.
Induction, by contact, and friction
2 factors that gravitational force depend on....
mass and distance
Opposite magnetic poles will __________.
What is attract?
What are two ways you can make an electromagnet stronger?
Bigger iron core, more wire turns/coils, stronger battery/more current
A way of rearranging electric charges within an object without touching it
What is a induction?
Tell the difference between a conductor and an insulator.
Conductors allows electric charge to flow, insulators do not
Gravitational Force (get stronger/weakens) as the distance between two masses increases.
Pick one!
Weakens
When an object is magnetized, what happens to the domains?
the domains are aligned or all facing the same direction
Draw the electromagnet setup. Include everything
Teacher will check
a material that allows electric charges to flow freely
What is an electrical conductor?
What is repel?
Why is gravity called an attractive force?
It pulls but it does not push
