Electricity
What is an "Electric Force"
An electric force is the push or pull of charged objects on each other.
What is a permanent magnet?
A permanent magnet is a magnet whose magnetism cannot be turned on and off.
What does "Repel" mean?
Repel means to push away from each other.
What does it mean when something is neutral?
When something is neutral, it does not have a positive or a negative charge. This means that the object does not have an electric charge.
If you try to touch the south poles of 2 magnets together, would they attract or repel?
The magnets would repel. Two poles of the same type always repel each other.
What is a "Conductor"?
A conductor is material, usually metal, that allows electrical charges to move easily.
True or False: When an object has more positive charges than it does negative charges, we would say that object has a positive electric force.
True!
What is the largest natural magnet on Earth?
The largest natural magnet on Earth is the plant itself!
What is an "Electromagnet"?
An electromagnet is a magnet whose magnetism can be turned on and off.
An object's electric charge can be positive, negative, or neutral.
Can a magnet attract something made out of plastic?
No, magnets only attract certain kinds of metal (mostly iron or steel).
What is a "Magnetic Field"?
A magnetic field is the space where the force of a magnet acts.
True or False: In an insulator, electric charges move easily.
False, in an insulator electric charges CANNOT move easily.
What happens if you move a magnet closer to a piece of metal?
If you move the magnet closer to the metal, the pull of the magnet on the metal increases.
What is a "Magnetic Pole"?
A magnetic pole is the point where the magnetic force is the strongest.
