Magnetism Vocabulary
Objects that have the ability to attract and repel
Magnetism
A form of energy that is used for lights, heating and motors
Electricity
What do magnets attract or repel
other magnets and metals such as iron, copper and steel
Describe how to light a light bulb
The wire, battery and light bulb must create a closed circuit by connecting all three together.
What type of magnet is the Earth most like?
a bar magnet
region in which the magnetic fields of atoms are grouped together and aligned because electrons are aligned.
Magnetic Domain
Type of electricity where electric charges that build up on an object
Static Electricity
magnetics are an example of what type of force
Why are magnets and electricity considered potential energy?
Magnets have energy based on how close they are to other objects
Electricity- electrons don't move unless a circuit has been created, which allows electrons to move away from each other and towards protons.
If you triple the number of wraps what happens to the the strength of an electromagnet?
the area where a magnet can act on other objects.
Magnetic Field
Part of the atom that contributes to electric charges
Electrons
the domains all face the same way when magnetized
Domains face different directions when unmagnetized.
A light will light up when electrons...
are flowing through a circuit
What part of an electromagnetic has potential energy for the circuit.
the battery
North and south parts of a magnet
Poles
The negative charges in the balloon attract the positive charges in the wall
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 that affect the force of magnetism
1. Bring magnets closer together
2. Use bigger magnets or add more magnets together
Draw and label the parts of an atom
Teacher will check or check your notes
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
