Electromagnetic Induction and Galvanometer Review

These flashcards cover key concepts and vocabulary related to electromagnetic induction and the role of the galvanometer in measuring electrical current.

Galvanometer

An instrument for measuring electrical current, used on electrical circuits to determine the intensity and direction of electrical current.

Electromagnetic Induction

The process of generating an electric current by moving a magnet through a coil, discovered by Michael Faraday in 1831.

Faraday’s Law

States that moving a magnet through a coil creates an electric current.

Factors Affecting Induced Voltage

Factors include speed of movement of the magnet, number of coil turns, and strength of the magnet.

Speed of Movement

A faster-moving magnet generates higher voltage.

Number of Coil Turns

More turns of the coil result in a stronger induced current.

Magnet Strength

A stronger magnet increases the effect of electromagnetic induction.

Real-World Applications

Examples include hydroelectric dams, wind turbines, and induction stoves.
