JEE Advanced Important Questions of Magnetic Effects of Current and Magnetism
FAQs on JEE Advanced Magnetic Effects of Current and Magnetism Important Questions
1. What are the concepts covered in Magnetic Effects of Current and Magnetism and how important are they from an exam point of view?
There are various key concepts covered in the chapter such as properties of magnetic field lines, the correlation of electricity and magnetism and how it was discovered, important laws of electricity and magnetism (like the Biot-Savart’s law), and how all these are applied in order to get to the solution of a problem. These are highly important from an exam point of view since they have been repeatedly asked in the JEE Advanced exams over the past few years and in different forms as well. There are also quite a few formulas and derivations that one needs to learn and remember while studying this chapter since those will come in handy to save you some valuable minutes when solving a question in the exam.
2. What are some guide books that the students should refer to while preparing the topic?
Just like for all the other topics covered in the JEE, there is absolutely no shortage of the sources you can refer to in order to study a given topic. It is however advised that you first finish reading everything in the textbook and only then move on studying from external sources. As far as Physics is concerned, Understanding Physics by DC Pandey (5 Volumes) and Concepts of Physics by HC Verma (2 Volumes) are two of the most recommended and used ones. Apart from all those, students can also benefit immensely from the different articles present on Vedantu, that provide topic by topic important questions, summary notes and more.
3. Do the students need to remember the definitions and the laws exactly as they are given in the NCERT for the JEE Advanced exam?
While remembering the exact statements of the laws and other important definitions is expected of the student for the board exams in class 12, the JEE advanced exam does not test the student in this manner at all. What is more important than knowing the definition by heart is the ability of the student to apply what the central meaning of the definition is and solve problems based on that. JEE Advanced is notorious for making even the simplest of concepts look pretty hard when the majority of the students end up getting the wrong answer for a seemingly straightforward concept. Thus when preparing for the JEE, rather than remembering the answers by heart, students must focus more or if they can apply the things mentioned in the formula in different types of situations.
4. Is it a good strategy to mug up almost all formulas without trying to get too much into how they were derived?
Students initially think that it is possible for them to simply learn every formula there is in this chapter and directly apply it in the paper rather than trying to derive some of them on their own. However, while it is true that remembering formulas does help save time in the exam, students have to realise that it is not humanly possible to completely mug up so many formulas and retain them for two years until you give the exam, since this is not the only chapter that you will be studying. It can also rather have an adverse effect on your marks if you make a little error while reproducing the formula in the paper, like changing a plus two or minus or something similar. To summarise we can say you should try to remember as many results as you can but also fully understand how you got to the result so that you can replicate that procedure in the time of the exam in case you forget the formula.
5. What are some last minute things to revise in this chapter?
Studying and understanding the chapter is only half the job done since revising it is almost just as crucial. However, you cannot fully revise everything that you have learned at the end of a few days before the exam and thus we have prepared a short list of the important concepts in this chapter that you should read before calling it done for this chapter.

With that, we’ve reached the end of this article and if you’ve solved all the questions mentioned in the pdf diligently, you should be more than confident of attempting these questions in the JEE Advanced. We wish every aspirant the best of luck and really hope this article was worth your valuable time. These answers are available at Vedantu website for free.
