Force and Motion
Review
A region of magnetic
force surrounding a
magnet is called the…
Magnetic
field
Electrically
charged
objects produce
motion because…
 They
pick up electrical charges
from other atoms (becoming
charged). They produce motion
because they have opposite
charges.
Electrical
charges
can result in….
discharge
repulsion
attraction
 True
or False: Electrically
charged objects push and
pull on all other charged
objects.
True
Every
magnet has two
ends or _________.
poles
True
or False:
Magnetism can be used
to generate electricity
by moving magnets in
and out of a coil.
True
 True
or False: A temporary
magnet created when current
flows through foam wrapped
around an iron bar is called
an electromagnet.
 False;
wire wrapped
around
What can this boy watch turn on a
compass to help him find magnetic

A
needle
 True
or False: A material or
device that attracts items
that contain boron or
phosphorus is called a
magnet.

False; iron, nickel, or cobalt


When a conducting wire is connected between
the positive and negative terminals of a battery,
one end of the wire becomes positively charged
and the other end negatively charged.

The difference in charge causes electrons to
move through the wire towards the positive
terminal of the battery, where they are removed
from the wire. The battery acts as a kind of
pump, pulling electrons from one end of the wire
and pushing them into the other.
This describes…
current electricity that
flows through a wire.
