This is the name of the positively charged particles
What are protons?
100
This is a closed path that electric current follows
What is an electric circuit?
100
This area of the magnet is where the force is the strongest?
What are the poles?
100
Scientists first discovered electricity because of the movement of this science tool.
What is a compass?
100
A magnet that has coils of current-carrying wire around an iron core is called this
What is an electromagnet?
200
When you rub two objects together, this charge particle is rubbed off or scraped off causing one object to be more positive and the other object to be more negative
What are electrons?
200
These objects allow for the flow of electricity to go through very well
What are conductors?
200
When you put like poles together this happens.
What is repel?
200
This is needed to rub onto to make a regular needle into a compass.
What is a magnet?
200
When you have more electricity (more energy with more battery packs) flowing through the coils, the strength of the magnet becomes STRONGER or WEAKER
What is STRONGER
300
When one object has a more negative charge and the other object has a more positive charge, the two objects do this
What is attract?
300
This electric pathway has only one path for its current to follow. If one of the light bulbs went out, none of the light bulbs would work.
What is a series circuit?
300
________, Nickel, and Iron are the three types of metal that are attracted to magnets.
What is cobalt?
300
Electrical energy comes from the constant flow of these charged particles
What are electrons?
300
When there are less coils the strength of the magnet is STRONGER or WEAKER
What is weaker?
400
The push or pull between objects that have different charges is called this
What is an electric force
400
This circuit has more than one path for the current to follow. If something blocks the charges along one path, the charges keep flowing along another path.
What is a parallel circuit?
400
This is the area where the magnetic force AROUND a magnet acts. If you were to sprinkle iron filing over this area, you should see a pattern of lines.
What is the magnetic field?
400
the letters "DC" for DC circuits stand for these two words
What is DIRECT CURRENT?
400
A device that changes electrical energy into kinetic energy (energy from movement) is called this
What is an electric motor?
500
When the objects have the same number of protons and electrons, we say that the objects have this type charge
What is neutral?
500
You need ________, strips of wire, and light bulbs to make a simple circuit.
What is a battery? or energy source?
500
This took that is used to find directions uses a magnet to point people into the right direction.
What is a compass?
500
Look at the following diagram.
Why would this circuit not work?
The battery is not connected to one positive and one negative side for a full circuit flow.
500
A machine that changes other forms of energy into electrical energy are called this.
