Friends, I will conduct a one model full test for the TN SET exam on 12/05/2024. If you wish you can attend this test.

This test is completely based on the exam pattern of TN SET 2024. So this test will surely help you.

Paper 1 : 50 Questions ( as per ugc net syllabus )
Paper 2 : 100 ( as per csir net physical science syllabus)

Friends, all the questions are taken from standard books, PYQ, Other popular readymade books, MS University proscribed study and reference books, MS University PG questions, etc.

Fees: ₹100 Only.

Questions available in Google forms. I will provide two links for paper 1 and 2 separately. And answer PDF with " solution" for problems will provide. And you can attend the test anytime, multiple times.

In addition to that I will send extra 100 mcq with a key.
How to join this test?

Friends click the link below and join this group and click the pinned message (payment details were given)and send a screenshot of that group with your email ID. That's it

Significance of Maxwell equations

Maxwell First Equation
Maxwell’s first equation is based on the Gauss law of electrostatic, which states that “when a closed surface integral of electric flux density is always equal to charge enclosed over that surface”

Maxwell Second Equation
Maxwell second equation is based on Gauss law on magnetostatics.

Gauss law on magnetostatics states that “closed surface integral of magnetic flux density is always equal to total scalar magnetic flux enclosed within that surface of any shape or size lying in any medium.”

Maxwell Third Equation
Statement: Time-varying magnetic field will always produce an electric field.

Maxwell’s 3rd equation is derived from Faraday’s laws of Electromagnetic Induction. It states that “Whenever there are n-turns of conducting coil in a closed path placed in a time-varying magnetic field, an alternating electromotive force gets induced in each coil.” Lenz’s law gives this. Which states, ” An induced electromotive force always opposes the time-varying magnetic flux.”

Maxwell’s Fourth Equation
It is based on Ampere’s circuit law. To understand Maxwell’s fourth equation, it is crucial to understand Ampere’s circuit law,



Consider a wire of a current-carrying conductor with the current I. Since there is an electric field, there has to be a magnetic field vector around it. Ampere’s circuit law states that “The closed line integral of magnetic field vector is always equal to the total amount of scalar electric field enclosed within the path of any shape”, which means the current flowing along the wire(which is a scalar quantity) is equal to the magnetic field vector (which is a vector quantity)
