Module 3 Test Flashcards
Magnet
An object that attracts iron and other materials that have magnetic qualities similar to iron
Magnetic force
A force of attraction or repulsion created by a magnet
Magnetic pole
The place on a magnet where the force it exerts is strongest
Magnetic potential energy
Stored energy due to interactions of magnetic poles in a magnet field
Magnetic Domain
Region in a magnetic material in which the magnetic fields of the atoms all point in the same direction.
Electric field
The invisible region around a charged object where an electric force is applied
Electric potential energy
The stored energy due to the interactions of charges in an electric field
Electrically charged
The condition of having an unbalanced amount of positive charge or negative charge
Induction
Charging an object without touching it
Electric insulator
A materiel through which electrons cannot easily move
Electric conductor
A materiel through which electrons easily move
Conduction
The transfer of charged particles between 2 conductors
Closed circuit
Circuit is complete and electric energy flows through the circuit
Open circuit
A circuit that is not complete and no electric energy flows through the circuit
Electric current
The movement of electrically charged particles
Voltage
The electrical potential energy difference per charge between two places on an electric circuit
Electromagnet
A magnet created by wrapping a current-carrying wire around a ferromagnetic core
Electric motor
A device that uses a magnetic field to transform mechanical energy to electric energy
Electric motor
A
Electric generator
A device that uses a magnetic field to transform mechanical energy to electric energy.
Direct current
An electric current that continually flows in a regular pattern
Alternating current
An electric current that changes direction in a regular pattern
Electromagnetism
The interactions between electric charges and magnets
