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 a current carrying wire wrapped around an iron core

What is electromagnet

100
Every magnet has two of these!
What are magnetic poles
100

Anything that takes up space

What is matter

200
The same number of positive particles as negative particles. (charge)
What is neutral?
200
this is a path in which electric charges can flow.
What is an electric circuit.
200

What is the flow of electrons called?

What is electricity

200

What happens if two like poles of a magnet come near each other?

They repel

200

The pushing force. Occurs when two like charges or poles come into each other’s electric or magnetic field

Repulsion

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

A material in which electrons can easily pass through

What is a conductor

300

Without changing the voltage on a battery, how do we increase the strength of the electromagnets used in class?

Wrap more wire around the nail to increase the current flowing around that part of the nail.

300
What happens if two opposite poles of a magnet come near each other?

They attract

300

The pulling force. Occurs when two opposite charges or poles come into each other’s electric or magnetic field

What is Attraction

400

An electric charge in motion. (electrons in motion)

What is electricity?

400

A material in which electrons cannot easily pass through

What is an insulator

400

What is it called when electricity flows continuously without interruption?

What is a closed circuit

400
Explain how you could make the magnetic force between two magnets weaker and stronger.
What is pull them closer and farther apart.
400

A force that attracts things towards each other. The more massive the object, the stronger the pull.

What is gravity

500

Why will a negatively charged object be attracted to a neutrally charged object?

The negative charge is attracted to the positive part of the neutral charge.

500

Which subatomic particles can be easily transferred between atoms? Explain.

What are electrons. Electrons are located on the outside of the atom.

500
When there is a break in a circuit. It can be called a _________ circuit.
What is an open circuit?
500

This is the region around a magnet in which the force of magnetism acts

What is the magnetic field

500

Electromagnet vs. Permanent magnet

An electromagnet is a magnet that is created by the movement of an electric current. A permanent magnet is a magnet that is continuously producing a magnetic field. An electromagnet is a magnet that can be “turned off”
