The mechanical force exerted by a magnetic field on a charged particle or magnetic object.

A machine that converts electrical energy into mechanical energy using a stationary coil of wire and a moving magnet.

Separating positive and negative charges by induction or conduction.

A device used to increase or decrease the voltage transmitted through electromagnetic induction.

A force that pulls objects toward each other, such as the force between opposite charges or poles of a magnet.

A property of matter that causes it to experience a force in an electric field, measured in coulombs (C).

A material that allows electric charges to flow freely, such as metals like copper or silver.

Conservation of charge

The principle stating that the total electric charge in a closed system remains constant.

The unit of electric charge in the International System of Units, equal to the charge of approximately 6.242×10^18 electrons.

A proportionality constant in Coulomb’s law, approximately equal to 8.99×10^9 N*m2/C2.

The law stating that the electric force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

The flow of electric charge through a conductor, typically measured in amperes (A).

The rate of flow of electric charge in a circuit.

A negatively charged subatomic particle found in atoms, responsible for electric current in conductors.

A device used to detect the presence of electric charge.

A law of electromagnetic induction stating that a changing magnetic field within a loop of wire induces an electromotive force (EMF) in the wire.

A material that does not allow electric charges to flow freely, such as rubber, glass, or plastic.

Inverse square relationship

A principle stating that a physical quantity (e.g., electric or magnetic force) is inversely proportional to the square of the distance from the source.

A law of electromagnetic induction stating that an induced current will flow in a direction that opposes the change in magnetic flux.

The size or amount of a quantity, often represented as the absolute value.

A small localized object with mass and charge, such as an electron, proton, or neutron.

A force that pushes objects away from each other, such as the force between like charges or poles of a magnet.

A mnemonic used to determine the direction of magnetic force, current, or field in relation to one another.

A method of expressing large or small numbers as a product of a coefficient and a power of 10, e.g., 1.23×10^4.

Van de Graaff generator

A device that generates high voltage by transferring electric charge to a large hollow metal sphere using a moving belt.
