Why Map Permanent Magnets Visually
Magnet types, domains and applications are easier to remember when they are linked on one page.
Build from your own material
Upload lecture slides, a PDF or class notes, and the AI turns them into a branched permanent magnets map.
See how the parts connect
Follow links between materials, magnetic domains, coercivity and applications in one structure.
Turn the map into practice
Expand any branch with AI, turn the map into a quiz, or make flashcards from the same notes.
How to Make a Permanent Magnets Map
Start from your course material or simply type the topic, and CogniGuide does the structuring.
- 1
Add your notes or type the topic

Study, quiz and export
Edit nodes, expand weak areas, take a quiz, then export as PNG or PDF.
Permanent Magnets Concept Map Overview
A permanent magnet keeps its magnetism without an external electric current. Its strength comes from aligned magnetic domains in materials such as iron, nickel, cobalt and rare-earth alloys. A useful map divides the topic into the main materials, the properties that describe them, and the everyday devices that depend on them.
- Materials: ferrite, alnico, samarium cobalt and neodymium magnets
- Domains: tiny regions whose magnetic moments point the same way
- Properties: remanence, coercivity and maximum energy product
- Applications: motors, generators, speakers and magnetic storage
- Limits: heat and demagnetization can weaken a magnet
Use a permanent magnets map to revise before an exam or to plan a lab report. CogniGuide can build a personalized version from your own notes, so you can test yourself on your course content.
Permanent Magnets Questions Answered
Quick answers on the topic, plus how to build your own map with CogniGuide.
What makes a material a permanent magnet?
A permanent magnet is made from a magnetically hard material whose domains stay aligned after the magnetizing field is removed. Coercivity measures how strongly the material resists demagnetization.
What is the difference between hard and soft magnetic materials?
Hard magnetic materials have high coercivity and stay magnetized, which suits permanent magnets. Soft magnetic materials, like pure iron, magnetize and demagnetize easily, which suits transformer cores and electromagnets.
Which file types can I use to build a permanent magnets map?
You can upload PDF, Word (DOCX), PowerPoint (PPTX), text or Markdown files, or an image of your notes. You can also type the topic directly.
Can I turn my permanent magnets map into a quiz?
Yes. Once the map is built, you can turn it into a quiz to test yourself, and the same notes can become flashcards. The free plan includes 5 creations a week.
