Electromagnetic induction is the process by which a changing magnetic field induces an electromotive force (EMF) in a conductor. This principle is fundamental to the operation of many electrical devices and systems, including transformers, electric generators, and inductors.
Historical Background
The phenomenon of electromagnetic induction was discovered by Michael Faraday in 1831. His experiments demonstrated that a changing magnetic field could induce a current in a nearby conductor, laying the groundwork for modern electromagnetic theory

1: What is the difference between self-induction and mutual induction?
Self-induction is the induction of EMF in the same coil due to a change in its own current, while mutual induction is the induction of EMF in a neighbouring coil due to a change in current in the primary coil.
2: How does the number of turns in a coil affect the induced EMF?
The induced EMF is directly proportional to the number of turns in the coil. Increasing the number of turns increases the EMF induced for a given rate of change of magnetic flux.
3: What are the best strategies for mastering electromagnetic induction concepts?
Regular practice, visualizing the magnetic fields and flux changes, understanding the principles through experiments, and using simulation tools can help in mastering electromagnetic induction concepts.
