7- Electricity and Magnetism

magnet field

• the space all around a magnet where the force of the magnet can act

• a type of energy that can be seen in the form of light

• the area where electric charges are stored

• a region where gravity is stronger than in other areas

electromagnet

• a coil that has a soft iron core and that acts as a magnet when an electric current is in the coil

• a permanent magnet made of steel

• a device that generates electricity using magnetic fields

• a type of magnet that only works at high temperatures

Magnetic North Pole

• An area pointed to by a compass based on the Earth's magnetism. This location will change over time.

• A fixed point on the Earth's surface that does not change.

• The point where the Earth's magnetic field is strongest and remains constant.

• A location that is determined by the position of the sun at noon.

series circuit

• An electric circuit with a single path

• An electric circuit with multiple paths

• A circuit that only works with batteries

• A circuit that can store energy

Electroscope

• An instrument used to detect electric charge

• A device for measuring temperature

• A tool for measuring distance

• An apparatus for generating electricity

Insulator

• A material that allows electrons to move freely

• A material that conducts electricity well

• A material in which electrons are not able to move easily

• A material that reflects heat effectively

parallel circuit

• A circuit that contains more than one path for current flow.

• A circuit that has only one path for current flow.

• A circuit that can only operate at high voltage.

• A circuit that is used to connect batteries in series.

magnetic pole

• The ends of a magnetic object, where the magnetic force is strongest.

• A type of electrical charge that attracts metals.

• A region in space with no magnetic field.

• The center of a magnet where the force is neutral.

Battery

• A device that converts chemical energy to electrical energy

• A device that stores electrical energy

• A device that generates heat energy

• A device that converts mechanical energy to electrical energy

electric circuit

• a complete, unbroken path through which electric charges can flow

• a device that stores electrical energy

• a type of electrical appliance

• a method of generating electricity
