Build Your Charges and Fields Map

Turn your textbook chapter or lecture slides into a map you can expand and test yourself on.

Map from your own material

Upload a PDF, Word file, PowerPoint or text notes, and the AI organizes the chapter into branches.

Expand any branch

Click a node such as electric field or field lines to add more detail with AI where your notes are thin.

Quiz yourself from the map

Turn the finished map into a quiz to check that you can explain charge, force and field relationships.

How to Make a Charges and Fields Map

Three steps take you from your notes to a study map you can revise from.

  1. 1

    Add your material

    Upload your chapter, slides or notes, or simply type the topic electric charges and fields.

  2. 2

    AI builds the map

    The AI groups charge types, Coulomb's law, field definitions and field line rules into branches.

  3. 3

    Study, expand and quiz

    Expand weak branches, edit wording, export a PDF and turn the map into a quiz before your exam.

Electric Charges and Fields Concept Map Overview

An electric charges and fields mind map organizes electrostatics around one core idea: charged objects exert forces on each other through an electric field. Charge comes in two types, positive and negative, and like charges repel while unlike charges attract. Coulomb's law gives the size of that force, and the electric field describes the force per unit charge at each point in space.

  • Electric charge: positive and negative, conservation, quantization of charge
  • Coulomb's law: force between point charges, dependence on distance
  • Electric field: definition, field of point charges, superposition
  • Field lines: direction, density, rules for drawing them
  • Conductors and insulators: how charge distributes and shields fields

Use the map to revise the chain from charge to force to field, and check each link with a worked problem. To build a map from your own textbook pages, CogniGuide can generate one in minutes.

Electric Charges and Fields Questions

Common questions about this topic and how to map it.

What is the difference between electric charge and electric field?

Electric charge is a property of matter that causes electric forces. The electric field is the region around a charge where another charge would feel a force. The field is created by charges and exerts force on charges.

How does Coulomb's law relate to electric fields?

Coulomb's law gives the force between two point charges, which is proportional to the product of the charges and inversely proportional to the square of the distance. Dividing that force by the test charge gives the electric field of a point charge.

Which file types can I use to build this map?

You can upload PDF, Word (DOCX), PowerPoint (PPTX), text or Markdown files, or images of your notes. You can also type the topic directly.

Is there a free plan to make my own charges and fields map?

Yes. The free plan allows 5 creations a week with no payment needed. From a finished map you can also turn the content into a quiz to test yourself.
