Why Use an Electromagnetism Map
A visual layout makes the links between electricity, magnetism and light easier to remember.
Build From Your Own Notes
Upload lecture slides, a textbook chapter PDF or a Word file and the AI builds the branches for you.
Clear Structure of the Topic
Charges, fields, circuits, induction and waves each sit in their own branch, so you see how the theory connects.

Electromagnetism Concept Map: Main Branches
Electromagnetism is the study of the electric and magnetic forces that arise from electric charge. It unifies two earlier fields: electricity, which covers charges, currents and voltage, and magnetism, which covers magnets and the forces they exert on moving charges. James Clerk Maxwell showed that changing electric and magnetic fields travel through space as electromagnetic waves, including light. A good map follows this path from basic charge to the wave theory.
- Electrostatics: charge, Coulomb's law, electric fields and potential
- Circuits: current, resistance, Ohm's law and Kirchhoff's rules
- Magnetism: magnetic fields, forces on currents and moving charges
- Induction: Faraday's law, Lenz's law and electromagnetic generators
- Maxwell's equations: the four laws that unify the theory
Use the map to revise before an exam or to check how each law links to the next. Create a map from your own lecture notes with CogniGuide to match your course exactly.
Electromagnetism Mind Map Questions
Answers about the topic and about making your own map.
What are the four Maxwell's equations?
They are Gauss's law for electricity, Gauss's law for magnetism, Faraday's law of induction and Ampère's law with Maxwell's correction. Together they describe how electric and magnetic fields are produced by charges, currents and changing fields.
How are electricity and magnetism related?
A moving electric charge produces a magnetic field, and a changing magnetic field produces an electric field. This link means the two are treated as one electromagnetic theory rather than separate subjects.
Which files can I use to build my map?
You can upload PDF, Word (DOCX), PowerPoint (PPTX), text or Markdown files, or images. You can also type a topic and the AI will build the map from it.
Can I turn my electromagnetism map into a quiz?
Yes. Once the map is built, you can turn it into a quiz to test yourself. The free plan includes 5 creations a week and needs no payment.
