Build Your Own Electromagnetism Map
Turn your textbook chapter or lecture slides into a clear map of electricity and magnetism.
Start from your own material
Upload a PDF, Word file, PowerPoint or text notes, and the AI extracts the main electricity and magnetism ideas.
Expand any branch
Open a node like Ohm's law or Faraday's law and let the AI add the equations, examples and related terms.
Test yourself with a quiz
Turn the finished map into a quiz, or make flashcards from the same notes before your exam.
How to Make an Electricity and Magnetism Map
Three steps take you from scattered notes to a map you can revise from.
- 1
Add your notes or topic
Upload your chapter, slides or image, or simply type electricity and magnetism.
- 2
AI builds the map
The generator groups charge, circuits, fields and induction into linked branches you can edit.

Study, expand and quiz
Expand weak branches, export a PNG or PDF, and test your recall with a quiz.
Electricity and Magnetism Concept Map Overview
Electricity and magnetism are two aspects of the same force, electromagnetism. A concept map of the subject usually starts with electric charge and then moves to electric fields and potential, current and resistance in circuits, and magnetic fields produced by moving charges. From there it reaches electromagnetic induction, the principle behind generators and transformers.
- Electric charge: positive and negative charge, conservation and Coulomb's law
- Circuits: current, voltage, resistance and Ohm's law
- Electric fields: field lines, potential and capacitance
- Magnetic fields: fields from currents, force on moving charges
- Induction: Faraday's law and Lenz's law
Use the map to review one branch at a time, then quiz yourself on the links between them. A map built from your own lecture notes with CogniGuide shows exactly what your course covers.

Electricity and Magnetism FAQs
Answers on the topic and on making your own map.
How are electricity and magnetism related?
A changing magnetic field produces an electric field, and a current produces a magnetic field. Maxwell's equations describe this unified electromagnetic relationship.
What is the difference between electric and magnetic fields?
Electric fields act on stationary charges, while magnetic fields act on moving charges. Both are vector fields with direction and strength at each point in space.
Which files can I use to build my own 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 a map from it.
Is it free to make an electricity and magnetism map?
Yes. The free plan lets you create 5 maps a week without payment. Paid plans raise those limits for heavier study use.
