1. Do I need to practise all the questions provided in Chapter 4 – Moving Charges and Magnetism?
Yes. These are the foundations of Physics. Although there are more than 1000 MCQs in Physics, questions from Chapter 4 – Moving Charges and Magnetism are the most frequently asked ones. You are required to focus on all the Chapters as this Chapter is the most scoring one compared to the rest of the Chapters. Creating a list of 50 to 60 questions and solving each one of them, one by one is the best way to practice these questions and score well in the exams.
2. What is the significance of using NCERT Books for Class 12 Physics Chapter 4 – Moving Charges and Magnetism?
Based on the guidelines of CBSE, NCERT books are the best for conceptual learning. These books can also be used as reference guides both for your school exams, the board exams, and even other competitive examinations. Most of the board exams are taken from these NCERT books. For revision purposes, during examination times, there is no other book better than those of NCERT. Also, NCERT books are way cheaper and easily available than any other books, thereby allowing students from all strata of life to avail themselves of compulsory education.

3. What is magnetic confinement as taught in Class 12 Physics Chapter 4?
Gravity itself is an invisible force that keeps everything together. What's more, it's 100 percent effective, which is why you can hold on to that plate of pancakes without them falling to the floor. We've built our entire technological world on the foundation of the ability to work with this invisible force.
Unfortunately, this is only a theoretical reality. In practice, we're constantly being bombarded by objects that are simply too heavy, and our only hope is to find an extra tiny bit of attraction between them. But when everything is moving at the same speed, there is no way to generate and use that tiny bit of extra strength.
4. What is magnetism as taught in Class 12 Physics Chapter 4?
The Science of magnetism involves the interaction between charged objects. At one extreme is something called paramagnetism where an object with no charge attracts a similar object with charge (though with less strength). At the other extreme, there is diamagnetism where an object with no charge attracts a similar object with a much greater charge (though with much less strength). While diamagnetism is quite different from electromagnetism, paramagnetism is very similar. It turns out that many natural phenomena are paramagnetic.

5. According to Class 12 Physics Chapter 4, what is Ampere’s Circuital Law?
Many people have a measurement system for using objects in their daily lives. For example, we put an object in front of our computer screen, set a magnet to the object, and use the distance between the two as a measurement. If we are measuring the distance between two fingers, then we use the distance between the two fingers to find the distance between the two objects. We can also say that the more finger distance, the smaller the object.
This is Ampere’s Law. This law states that the force required to accelerate a particle of matter is proportional to the square of the distance from that particle.
