Question

According to Maxwell’s hypothesis, changing of electric field give rise to-
A. An electromagnetic force
B. Electric displacement current
C. A magnetic field
D. Pressure gradient

Answer 1

Hint: To solve the above question where we have to find what will the change in magnetic field give rise to when we take the account of Maxwell’s hypothesis. So, first we will discuss what Maxwell's hypothesis is and then only we can come to the conclusion and find our answer.


Complete step-by-step solution:
In the above question we are asked that according to Maxwell’s hypothesis, what will the change in electric field give rise to-
So, first we will discuss what is Maxwell’s hypothesis
Maxwell's demon” also called magnetic method it is the well-known hypothesis that is put forward by J. C. Maxwell in 1871 which has an excited resonance and stormy discussion over and over again among many physicists for more than a century, but never has it been realized.
Electric field lines will originate on positive charges and terminate on the negative charges. The electric field is defined as the force per unit charge on any test charge, and the strength of the force is related to the electric constant, which is also known as the permittivity of free space. From Maxwell’s first equation we can obtain a special form of Coulomb’s law known as Gauss’s law for electricity.
According to Maxwell's electromagnetic theory, the EM waves propagations contain electric and magnetic field vibration in mutually perpendicular directions to each other. Thus, we can say that the changing electric field gives rise to the magnetic field.
According to Maxwell's hypothesis, the changing electric field gives rise to Magnetic field.
We know that \[F=qE\], where F is the force acting, q is the charge and E is the electric field.
We can also relate the magnetic field and force by\[F=qvB\], where v is velocity and B is the magnetic field.
So, we can obtain magnetic fields by changing electric fields.
Therefore, option C is correct.

Note: Electromagnetic waves are defined as the radiations that are in the form of waves of electric and magnetic energy and the Maxwell’s equations or the Maxwell’s hypothesis is the set of four equations that comprise a complete, overarching theory of electromagnetism.
