Why a Map Helps You Learn Electromagnetism
Electricity and magnetism are one connected subject. A map shows how the ideas depend on each other.
Build from your own notes
Upload lecture slides, a PDF chapter or typed notes, and the AI turns them into a branched map.
See the links between ideas
Branches for charge, fields, circuits and induction show how each concept leads to the next.
Turn the map into a quiz
Test yourself on the map, or make flashcards from the same notes before your exam.
How to Make an Electricity and Magnetism Map

Electricity and Magnetism Concept Map Overview
An electricity and magnetism concept map organizes electromagnetism into linked ideas. The subject starts with electric charge and electric fields, then moves to current and circuits. It ends with magnetic fields and how changing magnetic fields produce electric currents. Seeing these links helps you understand why each law follows from the last.
- Electric charge: positive and negative charge, and conservation of charge
- Electric fields: field lines, force on charges, and potential difference
- Current and circuits: resistance, Ohm's law, and series and parallel wiring
- Magnetism: magnetic fields around currents and forces on moving charges
- Induction: how changing magnetic flux creates an electromotive force
Use the map to revise before exams by testing yourself on each branch. CogniGuide can build a personalized electricity and magnetism map from your own notes.

Electricity and Magnetism Questions Answered
Common questions about the topic and about making your own map.
What is the relationship between electricity and magnetism?
Moving electric charges create magnetic fields, and changing magnetic fields create electric fields. This two-way link is called electromagnetism and is described by Maxwell's equations.
What does Ohm's law state?
Ohm's law states that the current through a conductor is proportional to the voltage across it, with resistance as the constant of proportionality. It is written as V = IR.
Which files can I use to make my map?
You can upload PDF, Word (DOCX), PowerPoint (PPTX), text or Markdown files, or an image. You can also type a topic and the AI will build the map from it.
Can I turn my electricity map into a quiz?
Yes. Once the map is created, you can turn it into a quiz to test yourself. The same notes can also become flashcards. A free plan is available.
