Electromagnetism

Hi guys!!!

This post is intended for students in class 12(but I highly recommend class 11 students to read it too, so that you have a guideline for the future).

The first chapter is electrostatics. Coulomb's Law, Potentials, Gauss' Law blah blah blah. Don't worry. I'll tell you what to do step by step. You must be thorough with vectors and mechanics. Click here to know more about Mechanics. If you are done then you won't face many problems in Coulomb's law. One section is done. Be very clear with the relation between V and E. Make sure you remember the formulae of V and E of various configurations with direction. Then comes Gauss' Law. This is really important. Practice a lot. And remember special results and derivations. Properties of conductors are important. Read theory from a good book like HCV. Capacitors is another important concept. Be clear with series/parallel connections, charge transfer, etc. Electrostatics in matter is yet another important concept. a lot of questions are asked on free charge and all which confuse those who are not clear with them. Reading theory and solving a lot of problems is recommended.

Then comes electric current. KCL, KVL, Ohm's Law, series/parallel and all related shit. It starts with a discussion of current conduction, drift velocity, electrons, basic properties of currents, etc. Not very important, but remember all formulae here. Then comes the circuit analysis part. Quite important. Practice a lot of questions involving KVL and KCL. Equivalent resistance calculation should be close to you. Practice many symmetry questions. They are common and easy. This chapter has less number of formulae and depends more on problem-solving.

Then comes magnetism. Be clear with currents and Electrostatics for this one. Quite similar to electrostatics. Lots of formulae and derivation(thanks to Biot Savart)- remember them all. Ampere's law is important. Practice a lot of questions and try out derivations(solenoid, wire,etc.) on your own. Direction matters a lot. Don't mess up with that. Practice questions on combined magnetic and electric field. These questions are common. Make sure you understand component splitting, vectors, etc. which are used heavily here. Electromagnetic Induction is easy. But it has a good weightage because it involves both currents and magnetism, Practice question based on calculating current with direction in different situations. This will help you clear KVL, magnetism and EMI all at a time.

Then comes JEE(Main) topics like EM Waves, Maxwell's Equations, etc. Just study NCERT well. And practice some past papers of JEE(Main). You are done.

Coming to the books must have books are NCERT and HCV. You must read HCV when the chapter gets finished in coaching(if you study at home, then just make HCV your coaching :p). If you need more practice, go for Arihant's book for Electromagnetism. Irodov is the final thing to do if you want a top 100 finish or aspire for Olympiads. But do it when you are done with everything else.

You can buy the books at a good price here(I have checked them all, and made sure they are the correct version). You can buy using these links-





This was Electromanetism. I  hope I covered everything. Comment any doubts/suggestions. Follow the blog for updates. I'll be posting a lot in the coming few days. Stay tuned!

All the best!!!
