Coulombian force and conductor

what’s effect of  coulombic forces on conductor medium ? amk niazi Ans: In a conductor, the coulombian  repulsive forces  pushes the valence electrons and the electrons move away from the center to the surface ie from the region of stronger force to the region of lesser force, creating a Faraday cage   Incoming search terms:what’s effect of coulombic forces on conductor [...]

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 [...]
