... Law of Conservation of Electric Charge: during any process, the net electrical charge of an isolated system remains constant ⇒ like charges repel and unlike charges attract each other ⇒ there are three ways to charge an object: charging by friction, charging by induction, and charging by contact ...

... The galvanomagnetic properties of bismuth containing admixtures of selenium have been investigated. From the values of the Hall constant in high fields it was established that one selenium atom changes the electron concentration in bismuth by 3 x 10~ :1:: 10% electrons per atom.. BASED on the result ...

... "circling" electrons to a changing magnetic field via classical induction (∝ dH/dt). The net effect is a precession of the circling electron, i.e. the normal vector of its orbit plane circles around on the green cone. ⇒ The "Lenz rule" ascertains that inductive effects oppose their source; diamagnet ...

Characterizing the Houghton College Cyclotron
... When ions pass through a magnetic field perpendicular to their plane of motion, they will follow a circular path. This allows them to be accelerated by an electric field over and over again in the same region of space. In a cyclotron, two “dee” shaped electrodes accelerate the ions. With each cycle, ...
