100
The tiny building blocks of everything
What are atoms?
100
This subatomic particle flows through the wire when an electric field is present.
What is an electron
100

This is the object that closes and opens the current in a circuit.

What is a switch.

100
This is a current carrying wire wrapped around an iron core
What is electromagnet
100

Explain how you could make the magnetic force between two magnets weaker 

What is pull them farther apart.

200
When there is a break in a circuit. It can be called a _________ circuit.
What is an open circuit?
200
this is a path in which electric charges can flow.
What is an electric circuit.
200

This is the SI unit of electric current.

What is Amperes or Amps

200

Demonstrate the first "right hand rule"

Thumb: Current

Four Fingers: Magnetic Field

200
Every magnet has two of these!
What are magnetic poles
300
When the positive and negative charges no longer balance. This is when negative charges are built up much more than positive.
What is static electricity?
300

Material that charged particles can easily flow though

What is wire, metal poles, anything metal. (Conductors)

300

This is the potential energy difference from one side of a circuit to the other, "pushing" the charged particles through.

What is voltage!

300

How is a solenoid different from an electromagnet

electromagnets have a metallic material placed within the coil of wire

300

The more field lines a magnet has, the ___________ the magnet is

stronger

400
An electric charge in motion. (electrons in motion)
What is an electric current?
400

These objects do not easily allow charged particles to travel through them, such as wood and rubber.

insulators

400

This measures how difficult it is for a current to pass through a part of a circuit

resistance

400

Demonstrate the second "right hand rule"

Thumb: Magnetic Force

Pointer: Current/moving charge

Middle: magnetic field

400

If two like poles are brought together, the potential energy does what?

Increases

500

This is when there is very little resistance in a circuit, leading to overheating and possibly fires or damage

short circuit

500

While classic diagrams show circuits travelling in the opposite direction, Electrons actually flow from the ______ terminal to the ________ terminal. (think about a battery)

What is negative to positive.

500

This is the unit of measurement for resistance

Ohms, or Omega

500
The production of an electric current by moving a magnet and a loop relative to each other is called this.
What is electromagnetic induction
500
