Magnets and Electricity Flashcards

Grade 3 · Science · Flashcards

Review the essential vocabulary for understanding magnets, magnetic force, and electrical circuits.

Flashcards

Magnet: An object that produces a force that attracts iron, nickel, and cobalt.
Magnetic force: The push or pull force produced by a magnet.
Magnetic poles: The two ends of a magnet — north and south — where the force is strongest.
Attract: When opposite magnetic poles (north and south) pull toward each other.
Repel: When like magnetic poles (north-north or south-south) push away from each other.
Magnetic field: The invisible area around a magnet where its force can affect objects.
Compass: A tool with a magnetized needle that points north by aligning with Earth's magnetic field.
Electricity: The flow of electrons through a material.
Circuit: A complete, closed path through which electricity can flow.
Conductor: A material that allows electricity to flow easily through it (e.g., copper, iron).
Insulator: A material that resists or blocks the flow of electricity (e.g., rubber, plastic, wood).
Switch: A device that opens or closes a circuit to control whether electricity flows.
Battery: A device that stores chemical energy and converts it into electrical energy to power a circuit.
Open circuit: A broken or incomplete circuit where electricity cannot flow.
