Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Electromagnetism is a process while electromagnetic induction is an effect. Electromagnetism is a process through which a material is magnetised (temporarily or permanently) by Electric current. For e.g. a copper wire wound round a soft iron core when supplied current, gets magnetised. This is Electromagnetism. Now, after being magnetised electrically the material like coil has its own magnetic field. When another coil comes in the vicinity of this magnetic field, it generates electricity (it must be noted that either the magnetic field or position of the second coil must be time varying within the field). This is called Electromagnetic induction i.e, state of being induced by an Electromagnet. I am attaching some pictures below hope they help you understand better.

sir, in physics chapter kinetic theory of gases is going to come in exam??

Yes questions can be there from Kinetic Theory of gases from Physics but it's not repeated every year & Will not carry more than 1/2 marks so prepare accordingly. Don't give more than 4-6 hrs to that Topic.

Swati rai
sir, electromagnetism is a topic or a chapter ,because according to PDF of marks distribution (which is given by u) it is written electromagnetism only
Electromagnetism is broad area which covers Electromagnetic Induction & Electromagnetic Waves also according to Class 12th NCERT syllabus. So, It's actually including both chapter EMI & EM Waves. So that's why I told Electromagnetism is important area for JAM BT exam. So take it as a chapter itself which have both EMI & EM Waves.
