Electric Field
A region of space around a charged object where other charged objects experience a force.
Electric Charge
An intrinsic property of matter that causes it to experience a force when placed in an electric field.
Coulomb (C)
The SI unit of electric charge, defined as the amount of charge transferred by a constant current of one ampere in one second.
Positive Charge
A type of electric charge that results in an object losing electrons.
Negative Charge
A type of electric charge that results in an object gaining electrons.
Magnetic Field
The vector field around a magnet or electric current, which affects the behavior of charged particles in the vicinity.
Tesla (T)
The SI unit of magnetic field strength.
Dynamo Theory
A theory describing the generation of Earth's magnetic field through the motion of molten iron in the outer core.
Field Lines
Imaginary lines that represent the direction and strength of a field; more dense lines indicate stronger fields.
Millikan Oil Drop Experiment
An experiment that measured the charge of the electron by observing the behavior of charged oil droplets in an electric field.
Right Hand Rule
A convention used to determine the direction of magnetic forces in relation to current and magnetic fields.
Ferromagnetic Materials
Materials like iron, cobalt, and nickel that can become permanently magnetized.
Oil Drop
Tiny droplets of oil used in Millikan's experiment to measure electric charge.
Maglev Train
A train that uses magnetic fields to levitate and propel itself, thus eliminating friction.
Positive Charge in Electric Field
The direction of the electric field is defined by the force experienced by a positive charge placed in that field.
Electromagnetic Force
The force experienced by a charged particle moving through a magnetic field.
Gravitational Force
The attractive force between masses; in the context of electric fields, it can act against the electric force on charged particles.
