a property that leads to electromagnetic interactions between the particles that make up matter
What is electric charge
100
In this type of current, charges flow in the same direction.
What is a direct current or DC
100
Frayed electrical cords create the risk of this
What is electrical shock
100
Natural materials such as iron, nickel, and cobalt can be turned into a type of magnet that can be turned into a permanent magnet when placed in a strong magnetic field
What is a ferromagnet
100
this results when electric currents and magnetic fields interact with each other
What is electromagnetism
200
ions that have more protons than electrons are said to be this
What is positively charged
200
Most household items run on this type of current
What is alternating current, AC
200
Salts in the human body make it a good conductor of this
What is electric currents
200
A magnetic field is created in this type of magnet when an electric current is passed through it.
What is an electromagnet
200
This device measures the strength and direction of an electric current in a wire
What is a galvanometer
300
copper is an example of this material through which electrical charges can move freely
What is an electrical conductor
300
this type of current can be controlled much more easily by devices called transformers and thus is more commonly used in homes
What is alternating current
300
Any bulb can burn out in this type of circuit without opening the circuit, in other words, the other bulbs will stay lit
What is a parallel circuit
300
The sun ejects charged particles, when the Earth's magnetic fields pull them toward the poles they interact with the particles in the Earth's atmosphere and create this beautiful light display
What are auroras
300
This process uses a changing magnetic field to produce an electric current
What is electromagnetic induction
400
this atom is said to be this because it has equal numbers of protons and electrons
What is neutral
400
A material's composition, the shape of it, and the temperature of it are factors affecting this
What is resistance
400
In this type of circuit, the electric charges have one path for the electric charges to follow
What is a series circuit
400
Magnetic poles are very similar to electric charges in that positive and negative charges will do this
What is attract each other
400
This uses movement, mechanical energy, to produce electrical energy
What is a generator
500
During a lightning storm, a negatively charged cloud ejects a lightning strike, it hits the top of a pole on the ground. The top of the pole has this charge.
What is a positive charge.
500
a long, thin, hot wire has less or higher electrical resistance
What is higher electrical resistance
500
Most circuits in homes are this type of circuit so that if one device goes out, electric charges can still flow to other parts of the circuit
What is a parallel circuit
500
A diagram of this shows the north and south poles of the atoms line up and point in the same direction creating a magnetic field
What is a domain
500
There will be more coils on the secondary side of this type of transformer in order to produce a higher voltage.
