To Know Lithium Ion Battery Working Principle and It's Latest Applications

SOLVED:(II) The betatron, a device used to accelerate electrons to high energy, consists of a circular vacuum tube placed in a magnetic field (Fig. 48 ), into which electrons are injected. The electromagnet produces a field that (1) keeps the elec- trons in their circular orbit inside the tube, and ( 2 ) increases the speed of the electrons when B changes. (a) Explain how the electrons are accelerated. (See Fig. 48 . ) In what direction are the electrons moving in Fig. 48 (give directions as if

in a betatron electrons are accelerated by an increasing magnetic flux density as in example 33 how must the field at the orbit relate to the average field in order that the electrons orbit 43592
