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