Lenz's law states that "whenever an e.m.f. is induced, the direction of induced current is such that it opposes the vary cause to which it is due."

Due to Chlorofluorocarbons (CFC) and CO2 in ozone layer, nascent oxygen are produced because they combine with water vapor and ozone and as a result ozone layer has depleted. Another most one is aerosol which has also depleted this layer.

Mostly in M.Sc. physics exam, the questions come from physics of B.Sc. and the concept from 12th. Read thoroughly the honors books and remember all the formula and concept and do all the answers of the questions given in the book. Be careful and confidential.

Try to understand the concept taught by your lecturers and solve more number of problems related to the concept. Have a goal and try to reach it. Try to discuss with your college staff and take good suggestions. For higher studies you can refer H C Verma, it is of IIT level.

Two equal and opposite charges separated by very small distance by which the electrostatic force can be ralealised is called electric dipole.

Electromagnetism is the property of an electromagnet. When electricity is passed through coiled (wire wounded) magnetic substance especially in magnet, it becomes electromagnet possessing the electromagnetic property.

Hi Vyom,
IIT is very well placed globally. No university in India has the reputation IIT has globally. However, if you get admitted to an university like MIT or GeorgiaTech, then go for these.
Good Luck.

Hi Mohit,
You can pursue your Ph.D only after you complete your MS, not directly after B.Sc. You can check for integrated programs but hard to find. MS programs will lead to Ph.D anyways. To study Masters in USA one has to obtain a four year Bachelor degree and take the GRE. You must check with the universities for admission requirements and acceptance of your degree, options are available. Most importantly you must focus on your grades. Improve your profile by doing high standard research oriented project work, publications, seminars and lots of extra curricular activities. Check other country options too.
