The Nature of Magnetism
This is the name of the
mineral that magnetic rock
contains.
This is the region of magnetic
force around a magnet.
This is a cluster of billions of
atoms whose magnetic fields
are lined up the same way.
This is a magnet made of
material that keeps its
magnetism.
This is a material that show
strong magnetic effects.
This is the smallest particle of
an element that has the
properties of the element.
Magnetic Earth
This is a device with a
magnetized needle that can
spin freely.
The poles of a magnetized
needle on a compass align
themselves with this.
This is located near, but not
exactly at the geographic
north pole.
This is a stream of highly
charged particles flowing at
high speeds from the sun.
This is a glowing region in the
atmosphere caused by
charged particles from the
sun.
This changes direction about
every 100,000 years.
Electric Charge and Static
Electricity
When a negatively charged
object and a positively
charged object are brought
close together they do this.
This is the field around an
electrically charged object
which exerts a force on other
charged objects.
This is an object in which
each positive charge is
balanced by a negative
charge.
This is movement of electrons
from one charged object to
another charged object by
direct contact.
This is the law which states
that no charges are created or
destroyed.
This is the loss of static
electricity as electric charges
move off an object.
Electrical Safety
This is a connection which
allows electricity to follow an
unintended path.
This is the coating on copper
wire which prevents people
from getting a shock as
current runs through the wire.
The third prong of a plug
connects the metal shell of an
appliance to this.
This is a metal rod mounted
on the roof of a building which
protects the building.
This device is added to a
circuit to prevent overheating.
These control the beating of
your heart.
Electricity, Magnetism, and
Motion
This is the ability to move an
object some distance.
When a current-carrying wire
is placed into this, electrical
energy is converted to
mechanical energy.
This is a device which uses
an electromagnet to measure
small amounts of current.
This is a device which
converts electrical energy into
mechanical energy and then
uses the mechanical energy
to turn an axle.
This device reverses the flow
of current through an electric
motor.
This is the name for the
arrangement of wires
wrapped around an iron core
in an electric motor.
Generating Electric Current
This is the process of
generating an electrical
current by moving a conductor
through a magnetic field.
This is a current which
consists of charges that move
back and forth in a circuit.
This is a device which
converts mechanical energy
into electrical energy.
This is a circular device made
up of many blades that are
turned by wind, tide, steam, or
water.
This is a type of energy
resource which results in no
waste.
This is an energy resource
that exists in a fixed amount.
