Electromagnetic Induction Lecture Notes

These flashcards cover key concepts and definitions related to electromagnetic induction, including principles, laws, and applications.

Electromagnetic Induction

The production of voltage (electromotive force) due to a changing magnetic field.

Faraday's Law of Induction

States that a voltage is induced in a circuit whenever relative motion exists between a conductor and a magnetic field, with the magnitude proportional to the rate of change of the flux.

Induced Voltage Factors

1. Number of Coils: More turns increase voltage. 2. Changing Magnetic Field: Movement affects induced voltage. 3. Speed: Faster movement generates more voltage.

Solenoid

A coil of wire that creates a magnetic field when electrical current is passed through it.

Fleming's Left-Hand Rule

A method to determine the direction of the magnetic force on a current-carrying conductor.

Magnetic Field

A region around a magnetic material or a moving electric charge within which the force of magnetism acts.

Lorentz Force

The force experienced by a charged particle moving through a magnetic field, causing it to move in a circular path.

Tesla (T)

The SI unit for magnetic field strength, defined as one newton per ampere meter.

Circular Trajectory

The path taken by a charged particle when a magnetic field provides centripetal force, causing the particle to move in a circle.

Electromotive Force (emf)

The voltage generated by a changing magnetic field, which drives current in a circuit.
