1st Year Physics Chapter 10 Notes (New Book 2025-26): Electromagnetism – All Punjab Boards

Electric motors, loudspeakers and the generators that supply power to homes all depend on one connection: electricity and magnetism are two sides of the same set of effects. Electromagnetism is Chapter 10 of the new Class 11 Physics textbook, prepared under PECTAA and taught in Punjab from the 2025-26 session.

This chapter can be hard to picture. Fields, forces and currents point in different directions, and a correct answer depends on keeping those directions straight in your head and on paper. Regular practice with written and numerical questions is what turns that difficulty into confidence.

The 1st year physics chapter 10 notes offered here are free and come in five parts: MCQs, short questions with answers, long questions with answers, solved numericals, and the solved exercise from the book.

The notes are prepared for the new textbook. Since the earlier Class 11 Physics book followed another syllabus, notes made for it are not a dependable match for this chapter.

Students from Faisalabad, Gujranwala, Sahiwal, Rawalpindi and the other Punjab boards all use the same book, so this one file is suitable for each of them. The sections below set out what each part of the notes does, which kinds of paper questions it relates to, and how to plan your study.

About Chapter 10 in brief

From its title, Electromagnetism concerns the link between electric currents and magnetic effects. In broad terms, moving charges produce magnetic fields, and magnetic fields can in turn act on moving charges and currents. This page explains how the notes can help you prepare; it is not a substitute for reading the chapter in your textbook.

What’s inside the 1st year physics chapter 10 notes

The Chapter 10 file contains five parts. Each is suited to a different kind of question, and using them in sequence gives your preparation a clear shape.

MCQs

This part has multiple-choice questions on Electromagnetism. Many of the trickiest choices in this chapter turn on direction or on which quantity depends on which, so MCQs are a good test of whether your understanding is sharp.

Attempt a full set without notes. For each question you get wrong, write one sentence explaining why the correct option is right. That short habit builds understanding faster than simply noting the score.

Short questions with answers

Short questions with answers make up this part. Here, a short question may ask you to define a term, give the unit of a magnetic quantity, or explain briefly what happens when a current or a magnet is changed in some way.

As you read the answers, pick out the cause and the effect in each. When you practise, try to state the cause first and the result second, in no more than three sentences.

Long questions with answers

This part provides long questions with detailed answers. Extended questions on electromagnetism may ask you to explain a law or principle, describe how a device works, or show how one quantity relates to another.

Diagrams carry a lot of weight in this chapter. As you study each long answer, redraw any figure yourself, adding arrows for directions. When you write your own long answers, make sure the text and the diagram tell the same story.

Numericals

This part is made up of solved numerical problems. Calculations in this area often combine several quantities at once, so organising the given data before you start makes a big difference.

Try each numerical yourself, then check the solution. Writing the known values in a small list at the top of your working, each with its unit, makes it easier to see which formula fits and which quantity you are actually being asked to find. If your answer is wrong, decide whether the slip was in the physics, the formula or the arithmetic, since each points to a different fix.

Solved exercise

This part works through the exercise at the end of Chapter 10 in the textbook. These questions show the variety of tasks the chapter expects you to handle, from definitions to calculations.

Write your own answers in rough before reading the solutions. Compare them honestly, and redo any question where your approach was different from the worked one.

Why these notes are useful

Electromagnetism benefits from repeated practice, and a single file with varied question types makes that practice easier to organise.

• Built for the new syllabus. The notes follow the 2025-26 PECTAA version of Chapter 10.
• Varied question types. You get objective items, written answers and calculations in one download.
• Worked solutions for comparison. Solved numericals and exercise solutions give you something concrete to check your own working against.
• Free. The file costs nothing on this page.

The notes are most helpful once you have read the chapter. Rely on the textbook and your teacher for explanation, and use the notes for practice and checking.

Which exam questions these notes help with

Below, each part of the file is matched with a question type that usually appears in the intermediate Physics paper. The final layout of the paper rests with your board, so look up its official pairing scheme for this session before building your revision around the table.

Guess papers often claim to know which electromagnetism questions will be set. These claims are not official. A thorough understanding of the chapter and a look at your board’s scheme are a more reliable guide.

How to study with these notes

Because so much depends on direction and diagrams in this chapter, a plan that includes regular drawing tends to help:

1. Read one section at a time. Stop after each section and write down its main idea in a single line.
2. Draw each figure yourself. Use arrows to mark the direction of current, field and force wherever the book shows them.
3. Try the textbook exercise in rough. Do this before you open any solutions.
4. Compare your attempt with the solved exercise. Note the questions where your reasoning took a different path.
5. Practise numericals methodically. List the known quantities with units, convert them to SI, write the relevant formula, substitute carefully, and finish with the unit. Ask whether your result is reasonable.
6. Practise from the short and long answers. Reproduce a few from memory, diagrams included.
7. Close with the MCQs. Revisit any idea that still causes mistakes.

Explaining a diagram aloud, even to yourself, is worth the effort. It is a simple way to check whether you understand the directions involved.

Who should use these notes

These notes are written for students in Punjab taking FSc part 1 with Physics, in either the pre-engineering or pre-medical group, using the new 2025-26 textbook. Other intermediate students studying Physics under a Punjab board can use them too.

Private candidates should first make sure their board has set the new book for their session. If it has, these electromagnetism notes will suit their preparation as well.

Download the notes

This page lets you download the Chapter 10 file free, without redirecting you anywhere else.

Store it with your diagrams and practice sheets for the chapter, so you can revise from your own work and the solutions together.

Frequently asked questions

Is Electromagnetism Chapter 10 in the new book?

Yes. In the PECTAA Class 11 Physics textbook used in Punjab from 2025-26, Chapter 10 is Electromagnetism, and these notes are written for it.

Which parts are in the Chapter 10 file?

You will find MCQs, short questions with answers, long questions with answers, solved numericals, and a solved version of the book’s exercise.

Does the Chapter 10 file cost anything?

No. There is no payment involved.

Why do I get directions wrong in electromagnetism questions?

Often the diagram has been skipped. Drawing the situation with arrows before you answer makes it much easier to keep current, field and force directions straight.

Do these notes work for the Lahore and Sargodha boards?

They do. All Punjab boards use the same textbook. The pattern of the paper is set out in your own board’s pairing scheme.
