Magnetism is a fundamental chapter in Class 9 Physics that explains the forces exerted by magnets and magnetic materials. This chapter is essential for students following the new 2026 Punjab Board syllabus, as it covers both theoretical concepts and practical applications.
In this chapter, students will learn:
-
Basic properties of magnets and the differences between various types of magnetic materials.
-
The concept of magnetic fields and magnetic field lines, and how to represent them.
-
Electromagnetism – the magnetic effect of a current-carrying conductor.
-
How Earth acts as a giant magnet, including magnetic declination and inclination.
-
Real-life applications of magnetism in technology, medical devices, and everyday life.
These notes are designed to help students understand concepts clearly, prepare for exams efficiently, and strengthen their problem-solving and practical knowledge.

Class 9 Physics Chapter 8 – Magnetism Short Questions
Q1: Define the magnetic field of a magnet.
Answer:
The magnetic field is the region around a magnet where its magnetic force can be detected. It is represented by magnetic field lines (lines of force) that show the direction and strength of the magnetic effect.
Q2: What is meant by magnetization?
Answer:
Magnetization is the process of making a magnetic material behave like a magnet by placing it in a magnetic field.
Q3: What is a magnetic field?
Answer:
A magnetic field is the region around a magnet where another magnetic object experiences a magnetic force.
Q4: What are diamagnetic materials?
Answer:
Diamagnetic materials are materials whose atomic magnetic fields cancel each other, so they do not produce a net magnetic field. Examples include copper and water.
