About magnetism and magnetic fields notes
GoConqr OriginalUsing Magnetism and Magnetic Fields notes
Start with Magnets for an introduction to poles, magnetic fields and field lines. Its short explanations provide a starting point before you move to notes on specific materials or effects.
The notes titled Magnetism and Electromagnetism include descriptions of magnetic properties and hard and soft magnetic materials. Magnetic Fields also covers Earth as a magnet. For a different topic, Electromagnetic induction discusses generating electricity through the movement of a conductor and a magnetic field.
Turn notes into study practice
After reading a section, close the note and write down what you remember. Reopen it to check your explanation and fill in anything you missed. If you want to test your understanding, switch to a quiz on the unit page; use flashcards when you want to work on short definitions.
Choose a note that matches the topic you are studying and work through it at your own pace.
Frequently asked questions
Which note is a good place to start?
Magnets is a useful starting point if you want to study poles and magnetic field lines. It describes the north and south poles and what a magnetic field is. After that, you can move to a note on magnetic materials or electromagnetic induction.
What topics do these notes cover?
The notes cover poles, magnetic materials, field lines, electromagnets and electromagnetic induction. Magnetic Fields includes Earth as a magnet, while Electromagnetic induction discusses generating electricity. There is also a note on the motor effect and one that mentions the Biot-Savart law and Ampere’s law.
Are these notes free to use?
Yes. Every note listed here is free to open and study without an account. The resources were made by GoConqr users. A free account can save your quiz scores and lets you make your own quizzes, mind maps, flashcards and notes.
Which students are these notes for?
The collection is mainly for secondary school students, with a few resources for primary pupils. The listed resources mention GCSE Physics, IGCSE Physics and A-level Physics. Check a note’s content to see whether it matches the topic and level you are studying.
