... As shown in figure two neutral metal spheres are in contact, both supported on insulating stands. When a negatively charged rod is brought near one of the spheres but without touching it, as in [b], the free electrons from the metal are repelled and drift slightly away from the rod, towards the righ ...

Topics 3b,c Electron Microscopy 1.0 Introduction and History
... Surface barrier detectors are solid state devices made up of semiconducting materials. A semiconducting material has a filled valence band and an empty conduction band- similar to ceramic materials. 1. When a BSE electron strikes the detector, electrons in the material move from valence to conductio ...

CHAPTER 27 SOURCES OF MAGNETIC FIELD • Magnetic field due
... Each element acts like a wire carrying part of the total current. It produces a magnetic field that is concentric, i.e., not down the tube. But, cancellation from all the diametrically opposite elements produces zero net field inside! So, there is no magnetic field inside the tube at all. Note that ...

Gauss* Law
... Gauss’ Law Surface S3.This surface encloses no charge, and thus qenc = 0. Gauss’ law requires that the net flux of the electric field through this surface be zero. That is reasonable because all the field lines pass entirely through the surface, entering it at the top and leaving at the bottom. Sur ...
