Learn Magnetism and Matter in Physics
Welcome to the fascinating world of Magnetism and Matter, a crucial chapter in the CBSE Class 12 Physics syllabus. This chapter acts as an essential bridge between foundational electromagnetic principles and the macroscopic magnetic properties we observe in everyday materials. Understanding magnetism is a major milestone in your physics journey because it explains the invisible forces governing everything from a simple compass to complex modern technologies like electric motors, MRI machines, and data storage devices. By exploring how matter responds to external magnetic fields, students gain a deeper, practical appreciation for the forces that invisibly shape our physical universe.
In this chapter, you will dive deep into the behavior of a bar magnet, examining its properties as an equivalent solenoid and exploring the continuous, closed-loop nature of magnetic field lines. A significant focus is placed on Earth's magnetism, where you will learn to calculate and define key elements such as magnetic declination, angle of dip (inclination), and the horizontal and vertical components of Earth's magnetic field. Furthermore, the curriculum covers the fundamental classification of materials into diamagnetic, paramagnetic, and ferromagnetic substances. You will also study the hysteresis loop, mastering concepts like retentivity and coercivity to determine which materials make the best permanent magnets or electromagnets.
The visual infographic beautifully summarizes two high-yield exam topics: the vector representation of Earth's magnetic elements and the distinct behavioral classification of magnetic materials based on their atomic dipole alignment in an external magnetic field. In your school and board exams, this chapter is heavily tested through conceptual reasoning questions, derivations, and numerical problems involving Earth's magnetic field components. Graphing questions related to the hysteresis curve (correlating B and H fields) are also extremely common. A quick tip for scoring high marks in this chapter is to create comparative tables for diamagnetic, paramagnetic, and ferromagnetic materials. Memorize how their magnetic susceptibility ($chi$) and relative permeability ($mu_r$) values compare to zero and one, as these consistently appear in multiple-choice and short-answer questions.
Mastering the nuances of Earth's magnetic field components and the intricate behavior of atomic dipoles can sometimes feel challenging to navigate alone. If you find the theoretical concepts or numerical problems in this chapter difficult, don't hesitate to seek expert guidance to boost your confidence.

Top Tutors who teach Magnetism and Matter
I am teaching Physics from last 5 years. And within a week after getting classes from me, student falls in love with the subject. Eagerly waits for the next class.
I am Anshu Gupta. I was working at a reputed school in Delhi for 23 year before relocating to Singapore in 2021. I was teaching Physics to Grade 12 students. I have taught more than 3000 students in the last 24 years.I worked in Singapore as a freelance tutor for last 1.5 years I'm teaching Physics to the students of IB, IP, CBSE, CIE, ICSE, AP. I have a vast 24 year experience of teaching Physics to high school students I create individual based strategies for my students for best results I can create my own study material Good conceptual knowledge of my subject is my strength. I believe in creating a friendly and comfortable environment for free interaction. I have a lot of experience of online teaching ( 4 years ) So the online lessons are as effective as face to face lessons I'm teaching Physics to the students of IB(HL and SL), IP(H1 and H2), CBSE(11th and 12th), CIE(A and AS), ICSE, AP(Physics C). I am teaching 3 H2 and 3 IB students online at present
I craft this review as an offering of gratitude for the transformative influence she has on me. Please note that my review is completely transparent and true to my personal experience. I approached her with the request of covering Calculus from Class 12 RD Sharma (which extends to over 500 pages!). It's a challenge to find educators who truly prioritize depth and detail in their instruction and are willing to navigate the complexity that CBSE demands. However, under her guidance, we covered each exercise comprehensively, thoroughly and meticulously. Her teaching skills are truly top-notch and her sessions are sharply structured. Complex problems were masterfully explained. She is reservoir of knowledge, and always has all the answers to my doubts. Additionally, she keeps me engaged throughout the class, giving me questions to work through and think about independently. But it's not just her teaching that mesmerizes – it's her respect for punctuality that sets the tone for disciplined learning. Each class, every session, begins on time and makes it clear that she is a seasoned professional with kernels of experience to her name. All in all, if you're looking for an exceptional teacher, in fact the best on this platform, Deepa ma'am should be your only choice.
In this competitive world education is the most important tool rather I say that it is sword by which one can win the competition.so I am in this field from last four years and teaching is my passion and even strength.My students are very happy with me in college as well as in tutions. Their results show it all. Students are always been encouraged to do studies one should not force them for the same.
Ramachandra sir's classes have helped me alot. It started with chemistry classes in Class 10 and continued in 11 th and 12 th for chem, phy and maths and it has been very helpful for me. He is patient at explaining questions and solving doubts( even if they are very very silly). I have been able to grasp concepts better after learning from his classes.
I am a teacher of Physics and having an experience of 12 years. I can teach Physics in very simple and conceptual way to students. I am M.Sc. in Physics, B.Ed., SET and CTET qualified. I worked as PGT Physics at APS Nasirabad and Kendriya Vidyalaya Banar, Rajasthan and Assistant Lecturer of Physics in Aakash Institute.
Prajeesha ma'am is an excellent teacher who makes Physics very easy to understand. She clarified all my doubts without any hesitation and helped me develop an interest towards the subject. She explains concepts clearly and solves numericals in class, making everything crystal-clear then and there. I would surely recommend her, especially for students requiring last-minute assistance before BOARDS.
I have completed MPhil in Physics and teaching in college for 6 years. I am giving online/ home tuition since 2015. I prefer mathematics .
