MAGNET
A material that is strongly attracted to a magnet.
FERROMAGNETIC
Who proposed the concept of electromagnetic induction?
MICHAEL FARADY
This part of a motor or generator is the rotating coil of wire where current is induced or flows.
ARMATURE
This type of magnet is created when a magnetic material is exposed to a magnetic field and retains its magnetism.
PERMANENT MAGNET
This is the area where the magnetic force is strongest on a magnet.
MAGNETIC POLES
An area around a magnet where magnetic force is present.
MAGNETIC FIELD
This term refers to the production of an electromotive force (EMF) in a conductor due to a changing magnetic field.
ELECTROMAGNETIC INDUCTION
These devices maintain electrical contact between the rotating armature and the external circuit.
BRUSHES
This type of magnet is created by running an electric current through a coil of wire.
ELECTROMAGNET
This is the flow of electric current due to a changing magnetic field.
INDUCED CURRENT
What is the direction of the magnetic field lines?
NORTH TO SOUTH
This device uses electromagnetic induction to convert mechanical energy into electrical energy.
GENERATOR
This part connects the brushes to the armature windings and allows current to flow in and out of the armature.
SPLIT RING COMMUTATOR
A device that converts motion into light.
GENERATOR
A device that converts electricity to spinning motion.
MOTOR
A magnetic is composed of arranged components called?
DOMAINS
What are the three main factors that might affect the magnitude of the induced current?
NUMBER OF LOOPS, MAGNETS, SPEED OF MOTION
This rotating part of a motor or generator produces a magnetic field to interact with the armature.
ROTOR
Changing of magnetic field is essential in inducing electric current. How will you increase the current using the concept of changing its magnetic field?
INCREASING SPEED
Term used for non-magnetic materials.
PARAMAGNETIC
There are different types of magnets. What is the name of the magnet which its magnetic power is turned on or off?
TEMPORARY/ELECTROMAGNET
What are the components of faraday's experiment?
MAGNET, COIL, GALVANOMETER
This stationary part of a generator or motor holds the coils or windings and provides support for the rotor.
STATOR
Reverses current direction in DC generators.
COMMUTATOR
What is produced around a conducting coil?
MAGNETIF FIELD
