Magnetism 1
The force a magnet exerts is called this.
What is magnetic force?
These type of poles ATTRACT each other.
What are OPPOSITE poles?
The flow of electric charges.
What is electric current?
Converts electrical energy into mechanical energy
electric motor
solve for x:
5x+5 = 35
x=6
These type of poles REPEL each other.
What are LIKE poles?
This type of magnet KEEPS its magnetism when removed from a magnetic field.
What is a permanent magnet?
How can you increase an electromagnets magnetic force?
increase coils(wraps of wire) or increase voltage
Moving an electromagnet through a magnetic field produces
current (electricity)

What are seahorses?
Ferromagnetic materials include these metals.
What are iron, cobalt, and nickel?
These regions of a magnet where the magnet is strongest.
What are the magnetic poles?
Is in closed circuits perpendicular to the flow of electrons
What is Magnetic field?
These are two types of transformers.
What is Step-Up and Step Down?
Who is Thomas Edison?
If a magnet is cut in half, these remain in the same orientation.
What are the magnet’s poles?
A magnet found in nature.
What is a lodestone?
Reversing the current on an electromagnet causes
Poles to switch
Used to switch the flow of current on an electric motor
What is a commutator?
