Q. State Maxwell's right hand cork screw rule.
Maxwells's right hand cork screw rule:
If a right handed cork screw is turn to advance along the direction of the current through a conductor then the direction of rotation of the screw gives the direction of the magnetic lines of force around the conductor.
the magnetic field at a dictance of 2cm from the axis of a straight conductor carrying current is 12mT.Find the currentin the conductor?
FORCE AND NEWTON'S LAWS 1. Ancient view objects tend to stop if they are in motion; force is needed to keep something motion. This was a natural thing to believe in beca
For germanium the forbidden gap is (A) 0.15ev. (B) 0.25ev. (C) 0.5ev. (D) 0.7ev. Ans: For germanium the forbidden gap is 0.7ev.
self induction of a coil depends by observing the effect of coil when put in series
The current induced in the conductor due change in magnetic field is called eddy current.we study more about this in electro magnetic laws.
Can radiations like gamma rays and x-rays be made prevented to enter a place by a magnetic field? Ans) Rutherford noted that gamma rays were not deflected (or at least, not easi
