Study Notes
Electromagnetic Induction
- Electromagnetic induction is the phenomenon where a changing magnetic field in a coil of wire induces an electromotive force (EMF).
- The direction of the induced current in electromagnetic induction is determined by Lenz's law.
- When the rate of change of the magnetic field through the coil increases, the induced EMF in the coil also increases.
Test your understanding of electromagnetic induction in physics with this quiz. Explore the phenomenon of induced electromotive force due to a changing magnetic field and discover how the direction of the induced current is determined by specific laws. See how the induced emf in a coil is affected when the rate of change of the magnetic field through the coil increases.
