Maxwell’s Equations – Integral form of Faraday’s law (Part 5)

So, if flux through any surface changes, an electric field is produced along the boundary of that surface. Again if there is a conducting material present along that boundary then induced field provides an emf that produces a current through that conducting material. Moving a bar magnet through a loop of wire produces electric current in the wire but if you hold magnet stationary with respect of the loop there would be no induced current.
The negative sign in Faraday’s law tell you that the induced emf opposes the change in flux – that is, it tends to maintain the existing flux. This is called Lenz’s law.

Recommended books for B.Sc physics Part-1

I have written several article where I have written about recommended books for various exams. This is one more article about books that a student can use for B.Sc. exams. Course structure of various indian universities vary but you can have books according to your needs and if you are planning to have a career in physics then you can consider buying books that you might benefit you when you go for your masters degree in physics. You can always hunt down your college library for these books.

Solving physics problems

Lots of time students me how can they solve physics problems and they say that they are having difficulty in solving physics problems. So here I decided to address this issue. Now first of all I would say that do not be afraid of the subject as I say again and again physics to me is most basic of all sciences and you must find the subject interesting and give yourself reasons for studying it for me it was just what I wanted to study till my masters degree and now I like helping students understanding physics.
