JEE Advanced Important Questions of Electromagnetic Induction and Ac

JEE Advanced is the next level for the students who clear the first round of the exams which is JEE Mains. This entrance exam is basically a computer-based exam with multiple-choice types of questions. As the exam date is approaching, students need to prepare for it with more effort. The best way to improve is by solving the important questions. Vedantu offers a repository of important questions to help you in the JEE Advanced examination.

Benefits of Electromagnetic Induction and Ac Important Questions On Vedantu

  • Important Questions available for each topic individually

  • Prepared by specialists in the industry

  • Solutions also provided to not only check the answer but also to show the best and shortest method to get to the solution 

  • Both types of questions are available (Single Correct and Multiple Correct)

  • Numericals, graph-based, circuit-based problems are available, which are frequently asked in the main exam.

  • Can be downloaded and viewed offline for people with an unstable internet connection.

This chapter is all about Induction, Energy, and Currents, and also in this, we will know about how to remove the time-independent assumption that we have been creating and allow the fields to vary with time and we can see a wonderful symmetry in the behavior of exhibited by time-varying electric and magnetic fields.  There are very interesting experiments like The experiments of Faraday and Henry, Magnetic flux, Faraday’s law of induction, and Lenz’s law and conservation of energy. The actual phenomenon of production of induction emf in a conductor when the electric flux is linked with that charge is known as electromagnetic induction. Magnetic flux is one of the scalar quantities and its SI unit is weber (Wb).  

This unit has a weightage of around 11 marks which is approximately 8.87% in the final examination. Our experts have drafted solutions to the important questions in an easy and understandable language to make it easier for the students to learn with ease. They have given the diagrams in a clear way for each and every topic wherever is required to support the solutions perfectly.

FAQs on JEE Advanced Electromagnetic Induction and Ac Important Questions

1. What is the difficulty level of this chapter when compared to other chapters in the syllabus?

When compared to other topics in the syllabus, electromagnetic induction and alternating current come sort of in the midway where it is not considered too difficult but also not too easy. It has been observed that students who get the knack of it right from the beginning are able to solve more complex questions like that asked in the advanced with relative ease, while others who are not as strong with electronics and the fundamentals that govern the laws of electronics are often found complaining about how difficult the chapter is. It is eventually the perception of the student that makes the topic hard or easy and not really the topic itself.

2. What is the approximate time in which one must be able to solve a given question based on Electromagnetic Induction and Alternating Current?

An interesting fact to note when checking their answers to the JEE advanced questions, is that many students, looking at the length of the solution tend to think that it is really a simple problem that needed to have been solved in under two minutes and feel sad if it wasn't the case for them. However, they must keep in mind that the exam is considered difficult not because of how lengthy the problems are but how tricky and layered they are. Even solving a solution that might take up only half a page can take 6 to 8 minutes considering how much thought process went behind it. Thus the student must not worry about spending too much time on a problem and try to get to the right solution if he believes he is on the right path, albeit at the cost of a few precious minutes.

3. What are the future applications of this chapter, at the engineering level?

When looking from an engineering point of view, this chapter is extremely important since it covers some very crucial topics such as the lenz law, self and mutual inductance, grouping of coils, among other things that are central to electrical, electronics as well as electronics and telecommunication engineering syllabus. Hence, students must keep in mind that if they actually enjoy and get the hang of this chapter and the concepts that it covers, then probably after they are done with the exam, they can think about choosing the engineering streams as their preferred choices.

4. What’s the next step after the student has completed solving all the questions mentioned on Vedantu?

This chapter can indeed be a tricky one and being confident about it will surely take some serious efforts put in by the student. Hence, even after completing the set of important questions, one may feel the need to quickly go through everything that has been covered in the chapter once again just for the reassurance that they have studied the chapter really well. Luckily, students need to waste their time finding such material because they can simply click here to visit a link that contains the summary notes for this chapter. Once the student has completed both, it is safe to assume that he is fully prepared to solve the questions on these topics if they come in the final paper.

5. How to make sure one at least doesn’t get a negative, if not positive, when solving questions based on the topic?

One of the primary reasons why the joint entrance exam is considered to be so tough is because of the strict penalty that is given for every incorrect answer. In the main exam, it is limited to a -1 for every incorrect answer, but in the advanced level, it can also go to a -2 for some particular questions. This can seriously lower your score despite getting a few questions right. In order to make sure that you don't fall into the trap and do not necessarily end up losing marks, here are a few things that you can do:

  • Don’t mark the answer unless you’re 100% sure of it.

  • In case you are able to boil it down to two options, you can think of attempting it since you’ve got a 50% chance of getting it right. Do so with care.

  • Avoid panicking and marking answers when nearing the finish mark. 

  • Understand you just need to score more, not solve/attempt more.

  • If you have absolutely no clue which way to head after reading a problem, immediately skip it and move to the nex one, and most importantly avoid guesswork at all costs.

And with that, we’ve successfully viewed all the important questions that you must solve when studying electromagnetic induction and alternating current. Making short notes of your own to refer to later on, (on or before the day of the exam) is also recommended. Connect with us at our social media links in order to know more.
