@AlfredCentauri But ofcourse induction is required. My textbook and so many people cant be wrong. So either my views about FIeld disturbances are wrong or i am missing a valuable point. Can you point out my mistake?

@AlfredCentauri My views about these Field "Disturbances" is that when a charged particles is accelerated, their is a change in field lines. These changes then continue to happen through out the Field and travel at the speed of light.These changes are called EM waves. These changes dont require induction to sustain themselves. The change can go on forever. So how does Induction fit in here.

Actually my primary question is answered but i would like to have rounded off understanding so that i dont get stuck thinking about these stuff again. See edit please. Thanks.

I see. So even though the Inverse Law is applicable, their is no energy loss which approximately leads to no loss in Intensity. Just one last question, You said that these waves are nothing but changes in Values of EM fields across space. SO that means the Field Exists infinitely as written by Alfred Centuari? Also do changes in E-field not Varying E-field also induce magnetic fields?

Sorry but i dont get it. How come the Plane wave is not affected by the Inverse law?

comment How do EM waves propogate?
Not able to edit so gonna write it here. So if i take the above model, then i run into a problem. Isnt Electric Field based on the inverse square law. So after some distance shouldn't its value decrease. I am not sure about the relation of E-field magnitude with EMR. But in this case its better to think about EM waves being constantly renewed with induction. Can someone clarify?

I understand your point. So a change in EM field will propagate at the speed of light, resulting in EM waves with no actual movement of Field, or rather movement of field was not possible to begin with. But then my understanding of EM fields inducing each other becomes wrong?

Thanks Mozibur and all others for the answers although they were not the answers I seek. but atleast I became aware about certain details you gave about what physics is all about nowadays
