Eddy currents and applications

What ere Eddy currents and what is their application?
Rahul asked
Answer: 
Eddy currents (also called Foucault currents) are currents induced in conductors, when the magnetic flux linked with a solid conductor changes. The change in magnetic flux can …

Magnetism and Laws of motion

“Can a body at rest make another body move,according to the laws of Newton this is impossible. The question is in magnetism, If it happens then why is it not predicted by classical mechanics?” (Priyoranajn asked) Answer: First of all I congratulate you for your genuine thought. It is the critical thinking which will lead […]
