What is static electricity?
What is an imbalance of electrical charges on a surface or within a material.
What are the names of the poles of a magnet?
What is the north and south pole.
What are the three parts needed to create an electric circuit?
What are the power source, the conductor, and the output device.
Power source (batter), conductor (copper wire), magnetic object (nail
What is an example of static electricity?
Walking on carpet, your body collects extra electrons from the carpet, so you are negatively charged. When you touch your dog, the electrons release in the form of a shock.
When like poles of a magnet are facing each other, what happens to them?
They repel each other.
What type of material is a good conductor?
What is copper or gold.
What causes the nail to become magnetized?
The electric current circulating the magnet.
Name the three parts of an atom.
Proton, electrons, and neutrons.
When two opposite poles are facing each other, what happens?
They attract each other.
Does the electric current flow from the negative side to the positive side or the positive side to the negative side?
What is the negative to the positive side.
Is an electromagnet a permanent or temporary magnet?
Temporary Magnet
What charge does an electrons have?
Negative charge and circles around the atom.
What is a feature that all magnets have? Hint, you can take a magnet, rub against a paper clip in one direction and then the paperclip becomes temporarily magnetized.
All the domains are facing the same direction.
Name two good insulators.
What is plastic or rubber.
What is the advantage of an electromagnet?
Can be turned on and off by stopping the flow of the electric current.
What charge do protons have?
Positive charge, found in the center of an atom.
What is the strongest type of magnet?
Neodydium magnets
What is a path for a current to flow along?
What is an electric current.
Name two ways an electromagnet can become stronger.
Wrap more coils around the nail by created a stronger magnetic field around it and by increasing the voltage of the power source.
