Electromagnetic Induction falls under Electricity and Magnetism portion of class 12 physics. Electromagnetic Induction Class 12 Physics Notes is designed according to the updated syllabus of 2080 and it covers all the important portion of the chapter. Students can easily prepare their notes, study for test or exams by taking the help of class 12 electromagnetic induction Notes.
Chapter – 18
Electromagnetic Induction
When a magnet is moved inwards or away from the coil, the galvanometer shows a suddendeflection. This deflection lasts so long as there is a relative motion between the coil and the magnet. No deflection is found to occur even when the magnet is placed within the coil or the magnet is kept stationary. Moving the magnet quickly towards or away from the coil, the deflection is more and if the magnet is moved slowly, the deflection is found to be less.
Chapter Overview
In this chapter we are going to learn the following concepts, ideas or topics;
Now let’s move on to the notes of electromagnetic induction. The PDF given below contains all the notes which includes all the topics mentioned in the chapter overview. We request students to use the notes of electromagnetic induction wisely for the purpose of making notes and preparing for the board examination.
You have to scroll down the PDF to view all the notes of electromagnetic induction. This PDF contains 14 slides in total which contains all the required notes of electromagnetic induction. It doesn’t contains the numerical problems so if you are searching for the numericals then you’ll find them in the next PDF given below.
Lenz’s Law
In Faraday’s Law of electromagnetic induction, we have discussed when and how much induced emf is produced but not about the direction of induced emf Russian scientist, H.F.E Lenz introduced a rule to find the direction of the induced e.m.f., which is known as Lenz’s Law. According to this law,” the direction of induced emf in any closed loop is such that it tends to produce a current that creates a magnetic flux to oppose the cause, i.e. change in magnetic flux that produces it.”
Electromagnetic Induction Class 12 Physics Numerical Questions
Those students who want to practice the numericals from electromagnetic induction chapter can practice the questions given in the PDF below. We have solved the selected numericals which will provide you the method of solving the numericals.
This PDF contains all the important numericals from electromagnetic induction chapter. In addition to the numericals it also contains all the required formulas used for solving the numerical problems of this chapter.
If you are willing to practise more numerical problems for your examination then you can practice the questions listed below.
These questions are provided for practising purposes. So we haven’t provided the solutions of the numerical problems. However, if you are facing problems while solving these numericals then we request you to copy the questions and paste it in Google to get the solutions of that numericals. If that doesn’t work then you can contact us through our telegram channel to get the solutions.
