Electromagnetic Induction Concept Map Explained
An electromagnetic induction concept map shows how a changing magnetic field produces an electromotive force in a conductor. The topic divides into magnetic flux, Faraday's law of induction, Lenz's law for the direction of induced current, and the devices that use these principles, such as generators and transformers.
- Magnetic flux: field strength multiplied by the area it passes through
- Faraday's law: induced EMF equals the rate of change of flux
- Lenz's law: induced current opposes the change that caused it
- Induced EMF: voltage created in a loop or coil
- Applications: generators, transformers and induction cooktops
Use the map to revise the relationships between flux, EMF and direction before an exam. To build a version from your own lecture notes, use CogniGuide.

Electromagnetic Induction Map Questions
Common questions about the topic and about making your own map.
What is electromagnetic induction?
Electromagnetic induction is the production of an electromotive force in a conductor when the magnetic flux through a circuit changes. Michael Faraday described this effect in 1831.
What does Lenz's law state?
Lenz's law states that the induced current flows in a direction that opposes the change in magnetic flux that produced it. This follows from conservation of energy.
Can I make an induction concept map from my own PDF?
Yes. Upload a PDF, Word file, PowerPoint or text file, or an image of your notes, and CogniGuide turns it into an interactive mind map.
Can the map become a quiz?
Yes. You can turn a CogniGuide mind map into a quiz to test yourself on laws, terms and applications. The free plan allows 5 creations a week.
