Question

According to Maxwell’s hypothesis, a changing electric field gives rise to

Answer 1

Hint: To solve these types of questions, we need to have knowledge about the exact hypothesis. Maxwell's hypothesis was a result of modified Faraday’s law of induction with the help of which it described the production of magnetic fields by a changing electric field.

Complete step-by-step solution:
According to Maxwell’s hypothesis, a changing electric field gives rise to magnetic fields. From Maxwell’s third equation which is derived from the Faraday’s law of induction, we know that “Whenever there are n-turns of conducting coil in a closed path which is placed in a time varying magnetic field, an alternating electromotive force gets induced in each and every coil and vice versa”. Hence, we can conclude that according to Maxwell’s hypothesis, a changing electric field gives rise to magnetic fields while a changing magnetic field gives rise to electric fields. Along with the other Maxwell equations, these equations can be said to form the foundation of electromagnetism, electrical circuits and optics which were named after a mathematical physicist whose name was James Clerk Maxwell. These equations are really important as they describe the nature of electric and magnetic fields and their production and are also used as a working principle for several electrical devices.

Note: The Maxwell equations that we all know are the fundamentals of electromagnetism and can be defined as combination of various other laws such as the Gauss’s law of electricity, Faraday’s law of electromagnetic induction, Gauss’s law of induction and Ampere’s law of current in a circuit.
