A complete path through which electric current can flow

Two kinds of magnetic poles

A tiny imbalance between positive and negative charge on an object.

A material with a low electrical resistance. It allows electrical energy to be passed through easily.

a force that opposes motion between two surfaces.

Two kinds of electric charge

A material that remains magnetic without outside energy being supplied.

a region around a charged particle or object within which a force would be exerted on other charged particles or objects.

The influence created by a magnet that exerts forces on other magnets

A fundamental property of matter that can be either positive or negative

the region of space surrounding a object in which another object experiences a force of gravitational attraction.

unit of electrical potential energy

Using a moving magnet to create electric current or voltage

determines how much current flows for a given voltage

unit of electric current

A magnet made with wires and an electric current

A metal, like iron, which has strong magnetic properties

a device that converts mechanical energy into electrical energy

a device used to tell if an object is charged
