The correct matching of Column-I with Column-II is:
(4) ()
Here's the breakdown:
- A) Faraday's law: Faraday's law of electromagnetic induction states that the induced EMF is proportional to the rate of change of magnetic flux. The mathematical expression is:
(\oint E d \ell=-)
So, ().
- B) Ampere-Maxwell law: This law is an extension of Ampere's law, which includes the displacement current term. It is expressed as:
(\oint B d \ell=\mu_0 I+\mu_0 \varepsilon_0 )
So, .
- C) Gauss's law for magnetism: This law states that the net magnetic flux through a closed surface is zero, implying there are no magnetic monopoles. The mathematical expression is:
(\oint B d A=1)
So, ().
D) Gauss's law for electrostatics: This law relates the electric flux through a closed surface to the charge enclosed by that surface. The mathematical expression is:
(\oint E d A=)
So, D P.
