The attraction or repulsion
created by spinning electric
charges.
What is magnetic force?
One of two points, such as the
ends of a magnet, that have
opposing magnetic qualities
What is magnetic pole?
A device that converts
mechanical energy into electrical
energy.
What is an electric generator?
A device that converts electrical
energy into mechanical energy.
What is an electric motor?
The interaction between
electricity and magnetism.
What is electromagnetism?
The process of creating a current
in a circuit by changing a
magnetic field.
What is electromagnetic
induction?
Any material that attracts iron or
materials containing iron.
What is a magnet?
A device that increases or
decreases the voltage of
alternating current.
What is a transformer?
Whether a material is magnetic or
not depends on this.
What is the material’s atoms?
As electrons move they make
this.
What are magnetic fields?
By increasing the electric current
in the wire you are also doing this
to the solenoid.
What is increasing the magnetic
field?
A galvanometer uses this to make
the relationship between electric
current and magnetic fields.
What are magnets?
What can you make visible by
sprinkling iron filings around a
magnet.
What are magnetic field lines?
Faraday’s experiments showed
that magnetic fields are made
when the electric field does this.
What is changes.
A compass needle responds to a
magnetic field, because the
compass needle is this.
What is a magnet?
This is created when a magnet
moves through a coil of wire.
What is an electric current?
This is created when a wire
moves between the poles of a
magnet.
What is an electric current?
This will demagnetize a magnet.
What is heat or drop?
A coil of wire with an electric
current is called this.
What is a solenoid?
A coil of wire that has a soft iron
core that acts as a magnet when
an electric current is in the coil is
this.
What is an electromagnet?
Increasing the number of loops
per meter in the solenoid does
this to it.
What is strengthen the solenoid’s
magnetic field?
A step-up transformer has more
coils in this.
What is the secondary coil?
Compasses work because the
earth acts like this.
What is a magnet?
A step-down transformer has
more coils in this.
What is the primary coil?
