What is the biggest source of energy for the Earth?
Sun
What kind of force do magnet give?
Magnetic force field
Will this circuit work
Look at board #1
no
What is the thing that closes and opens the current in a circuit.
Switch.
Every magnet has two of these
Poles
What is energy?
Power to make things move
North and south poles do this
Attract
this is a path in which electric charges can flow.
Circuit.
This is the SI unit of electric current.
Voltage
Electric Current move easily in these.
Conductors
Everything is made up of these things....
Atoms
This is the reason magnets might repel each other.
Same Poles are facing each other
Temporary magnet
An electric charge in motion (moving it is called....)
electric current
Name one variable that affects the magnetic force
Strength, size, distance....
Name at least 2 things that could slow the flow of electrons in a circuit. (Insulator)
wood plastic rubber
In this circuit, devices are connected so there is only 1 closed path for current to follow. Board #2
Series
A current carrying wire wrapped around an iron core is called this.
Electromagnet.
Name two types of energy
Ms. A will let you know.
Metal materials that are magnetic (3)
Iron, steel, nickel
This subatomic particle flows easily in a circuit.
Electron
This is a circuit where there is more than one close path for a current to follow. Board #3
Parallel
This is a measure of the amount of electrical energy transferred by an electric charge as it moves from one point to another in a circuit.
Voltage
