100
The same number of positive particles as negative particles. (charge)
What is neutral?
100

The ______ particles in storm clouds tend to gather at the top of the cloud while the ________ particles tend to gather at the bottom of the cloud.

What is positive and negative?

100

To push away

What does repel mean

100

Point towards this charge

What is negative

100
Every magnet has two of these!
What are magnetic poles
200
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?
200
This is a movement of a static charge from from place to another
What is static discharge
200
Name things (2) that electrons flow easily through. Examples
What is wire, metal poles, anything metal.
200

Points away from this charge

What is positive?

200
This is a current carrying wire wrapped around an iron core
What is electromagnet
300

Two things that electric force depend on

What is charge and distance?

300
This is an imbalance of electric charge (-) on an object
What is static charge
300
Name at least 2 things that could slow the flow of electrons in a circuit.
wood plastic rubber
300

A negative and a positive charge are brought near each other

What is a dipole?

300
Explain how you could make the magnetic force between two magnets weaker and stronger.
What is pull them closer and farther apart.
400
These are the two ways an object can be charged.
What is charging by contact & charging by indcution
400

How does a compass work?

It points to the earth's North magnetic pole

400
When field lines are placed farther apart?

What is a weaker force?

400
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

What four things do we need to remember about magnetic fields?

1. Start on north pole and end on south pole

2. Don't cross

3.  Form closed loops

4. stronger magnetic field when lines are closer to each other

500

Lines are evenly spaced and parallel

What is a uniform field?

500

The space around a magnet in which magnetic forces operate

What is a magnetic field
