Study Plan

1
Day 1–2

Learn the Theory

Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: 1. Classification of Magnetic Substances, 2. Magnetic Induction, Magnetisation, and Magnetic Intensity, 3. Properties of Dia-, Para-, and Ferromagnetic Substances.

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 44 questions available for this chapter.

3
Day 4

Revise & Test

Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.

Day 7

Spaced Revision

Come back to Magnetic Classification of Substances after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • All substances belong to one of the three magnetic classes.
  • Diamagnetic substances are repelled by a magnet.
  • Paramagnetic substances are weakly attracted by a magnet.
  • B measures magnetic flux density inside a substance.
  • M is magnetic moment per unit volume.
  • H measures the magnetising field strength.
  • Diamagnetic substances are weakly repelled.
  • χm is small and negative.
  • μr is slightly less than 1.

Common Mistakes to Avoid

Every magnetic substance belongs completely to only one class, so diamagnetism does not exist in paramagnetic or ferromagnetic substances.

Diamagnetic substances are attracted by a magnet because all magnetic materials are pulled toward stronger field regions.

Paramagnetic substances are repelled by magnets because they are only weakly magnetic.
