Objects that have the ability to attract and repel
Magnetism
True or False: Electrostatic forces can attract AND repel objects
True
What do magnets attract or repel
other magnets and metals such as iron, copper and steel
Draw how to light up a light bulb with a wire and a battery
The wire, battery and light bulb must create a closed circuit by connecting all three together.
What happens to the strength of an electromagnet when you add more wraps (more coils)
It gets stronger
Draw Magnetic domains
1. Magnetized
2. Unmagnetized
---> ---> ---> (arrows face the same direction)
---> <--- <--- ---> (arrows face different directions)
Type of electricity where electric charges that build up on an object
Static Electricity
magnetics are an example of what type of force
Magnets
Electricity
Gravity
If you triple the number of wraps what happens to the the strength of an electromagnet?
Draw a magnetic Field
Magnetic Field
Part of the atom that contributes to electric charges
Electrons
What is a non-contact force?
A force that can push or pull without touching another object
Explain why a light will light up when connected properly
Electrons are flowing through the circuit
What part of an electromagnetic has potential energy for the circuit.
the battery
1. Draw 2 magnets attracting (label north and south)
2. Draw 2 magnets repelling (label north and south)
1. N-S
2. S-S or N-N

Magnetism and electrostatic forces are similar in what ways?
answers will vary
What part of a circuit contains the potential energy for the whole circuit
battery
Give an example of how you know a magnetic exerts a force
answer vary...teacher will check
2 variables to strengthen force of a magnet
1. Bring magnets closer together
2. Use bigger magnets or add more magnets together
Draw and label an atom
Atom
If you cut a magnetic into 6 pieces you get what?
6 smaller magnets
How do you know an electric circuit has been set up correctly? If you have a wire, a battery and a light bulb?
If the light bulb lights up
What is happening inside an electromagnet to create a magnetic field?
Electrons are moving, which align the magnetic domains inside the core, which then acts as a magnetic field
