Magnetic Basics
This is the region around a magnet where magnetic forces can be detected.
Similar to the Electric Field Lines, this indicates the strength of the magnetic field.
What is the closeness of the magnetic field lines?
This device uses an electric current to create a temporary magnet.
What is an electromagnet?
These types of devices use the back and forth motion of electromagnets to produce sound.
What are speakers or headphones?
When looking at magnetic fields, we used these to help us visualize the magnetic field around a bar magnet.
What are arrows?
OR
What are iron fillings?
This is the region(s) of a magnet where the magentic force is the strongest.
What are the Magnetic Poles?
This instrument uses the Earth's magnetic field to align and show direction.
What is a compass?
Increasing this will increase the strength of the Electromagnet?
What is increasing the electric current?
OR
What is increasing the number of loops around a bolt?
This type of device converts ELECTRICAL ENERGY into MECHANICAL ENERGY.
What is an Electric Motor?
When looking at a magnetic field diagram, the field lines point from _____________ to ________________.
What is the North Pole to the South Pole?
You are presented with two magnets that have their North Poles pointed towards each other. What type of magnetic force is being used?
What is a repulsive force?
Earth's Magnetic North Pole is located here.
What is Earth's Geographic South Pole?
We used a battery, magnet, wire, and _____________ to create an electromagnet.
What is an iron bolt?
This type of device converts MECHANICAL ENERGY into ELECTRICAL ENERGY.
What is an electric generator?
This happens to a magnet when it is broken into 2 new pieces.
What is two new magnets are created with new poles?
These are the two biggest factors that affect magnetic strength.
What is distance and material?
This layer of the Earth is what developed Earth's magnentic field due to the movement of hot iron and nickel.
What is the core?
We use this Rule to determine the direction in which the electric current is moving.
What is the "Right Hand Rule"?
These are the parts of an electric motor that rub against the commutator as it spins.
What are brushes?
What is they combine?
This type of material is strongly attracted to magnets and contains iron.

Extra 200 if you can give 2 examples of it
What are Ferromagnetic Materials?
Earth acts like this type of magnetic due to the flow of electric currents.
What is an electromagnet?
Unlike permanent magnets, electromagents have this ability.
What is the ability to turn on and off?
What is an electromagnetic force?
Moving this near a current-carrying wire effects the magnetic field of the wire.
