100
The two ends of the magnet.
What are the magnetic poles?
100
Three examples of this are iron, nickel, and cobalt.
What is ferromagnetic material?
100
How are electric charges similar to magnets?
The both repel same and attract opposites
100
The path that an electric current takes
What is an electric circuit?
100
Water power, solar power and wind power are all examples of what?
What is renewable resources
200
The magnet always has these two poles when it is broken
What are north and south poles?
200
The three parts of this are a solenoid, a power source, and a ferromagnetic object.
What is an electromaget?
200
What are the charges on both a proton and an electron?
proton = positive electron = negative
200
What are the 4 parts of an electric circuit and give examples of each.
resistor = light bulb wire = copper power source = battery switch = light switch
200
What are the three types of nonrenewable resources and the general name for them.
coal, petroleum, and natural gas = fossil fuels
300
The force that surrounds a magnet
What is a magnetic field?
300
How are magnetism and electricity related?
an electric current produces a magnetic field.
300
What is the charged particle that can move in an atom?
an electron
300
What are the two different types of circuits?
series and parallel
300
Electricity takes an unintended path
What is short circuiting?
400
Heating and dropping a magnet will have this result.
What is destroying a magnet?
400
What are the three ways to make an electromagnet stronger?
more coils, more batteries, stronger ferrmagnetic material (iron)
400
What is the flow of electrons?
an electric current
400
What type of material allows electrons to flow more freely through it?
a conductor
400
This type of current in produced by a battery
What is direct current
500
The alignment of the billions of atoms in a materials that can potentially create a magnetic field
What is magnetic domain?
500
Creating a current by putting a conductor into a magnetic field
What is electromagnetic induction
500
What is static electricity and static discharge?
Static electricity = build up of charge in an object static discharge = the loss of static electricity
500
Describe the differences between a series and parallel circuit
series = one path, light bulbs dim when you add more, more resistance, light bulb goes out if other ones go out parallel = more than one path (branched wires), no change in resistance, light bulbs stay lit when one goes out, no change is brightness when there are more added
500
Describe friction, conduction and induction
transfer of electrons by friction=rubbing conduction=direct contact induction=electric field
