What are magnetic, electric-charge, electric-circuit, and electromagnetic?
100
True/False:
A magnet always repels magnetic material.
What is false?
100
The two types of electric-charges.
What are positive and negative?
100
A circuit in which electricity flows from a power source to light up a light bulb.
What is a complete circuit?
100
The type of interaction which allows large magnets in junkyard to pick up then drop magnetic material.
What is electromagnetic interaction?
200
The type of interaction when magnets pull or push each other.
What is magnetic interaction?
200
A magnet attracts another magnet. This happens when the magnet is flipped over and then brought near another magnet again.
What is repel?
200
True/False:
"An electrically-charged object attracts other objects."
What is true?
200
This flows through an electric-circuit.
What is electric current?
200
The flow of this through a loop of copper wire creates a magnetic field.
What is electric current?
300
The type of interaction that occurs when a balloon sticks to the wall after you rub the balloon on your hair.
What is electric-charge interaction?
300
This happens when two magnets with the same pole are brought near each other.
What is repel?
300
The charge of a balloon that is attracted to a balloon that has a negative charge.
What is positive?
300
A circuit in which one light bulb is connected to the next light bulb. When one light bulb is disconnected from the power source, all other light bulbs go out.
What is a series circuit?
300
This makes a coil of copper wire have a stronger electromagnetic effect.
What is increase the number of loops?
400
The type of interaction that occurs when an electric-current flows through a loop of copper wire.
What is electromagnetic interaction?
400
This happens when two magnets with the opposite pole are brought near each other.
What is attract?
400
The effect of a charged balloon when it is brought near another balloon with the same charge.
What is repel?
400
A circuit in which each light bulb is individually connected back to the power source. Even when one light bulb is disconnected from the power source, the others remain lit.
What is a parallel circuit?
400
Another way to make an electromagnet have a stronger magnetic force.
What is increase amount of cells/batteries/electric current?
500
The type of interaction that occurs when you plug your phone into an outlet to charge it?
What is electric-circuit interaction?
500
The two poles of a magnet.
What is north and south?
500
True/False:
"Electrically-charged objects can only interact with objects that are made of metal."
What is false?
500
A material through which electric current can flow.
What is a conductor?
500
The name for the electromagnetic phenomenon that occurs near the poles of the earth.
What is the northern lights/aurora borealis/southern lights/aurora australis?
