Induced EMF in a Wooden Ring with Time Varying Magnetic Field

Click For Summary
A wooden ring exposed to a time-varying magnetic field will indeed experience induced electromotive force (EMF) due to the changing magnetic field, which generates an electric field. This phenomenon occurs regardless of the presence of a conductor, as the electric field exists even in a vacuum. Understanding this concept can be enhanced by studying Maxwell's equations, which describe the relationship between electric and magnetic fields. While a conducting loop is necessary for an induced current to flow, the induced electric field itself is present in the wooden ring. The key takeaway is that the changing magnetic field is the source of the induced electric field.

Suppose i have a wooden ring and a time varying magnetic field is passed through it. Then will there be induced emf.
 
Physics news on Phys.org
Sure. The changing magnetic field creates an induced electric field.
 
The induced EMF would be present even in a vacuum! :)
 
That's what written in the book. The ans is yes. but i am not able to appreciate the fact. WHY?
 
As I said before, it's the changing magnetic field that induces an electric field. (To understand that better, explore Maxwell's equations.) Perhaps you are thinking of an induced current: that will require a conducting loop. But the electric field is there, conducting loop or not.
 

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
