An example of induction using a negatively charged object and an initially-uncharged conductor (for example, a metal ball on a plastic handle). (1) bring the negatively-charged object close to, but not touching, the conductor. Electrons on the conductor will be repelled from the area nearest the charged object. (2) connect the conductor to ground. The electrons on the conductor want to get as far away from the negatively-charged object as possible, so some of them flow to ground. (3) remove the ground connection. This leaves the conductor with a deficit of electrons. (4) remove the charged object. The conductor is now positively charged. A practical application involving the transfer of charge is in how laser printers and photocopiers work. This is a good web page that gives a nice description of how a photocopier works: • University of Delaware Why is static electricity more apparent in winter? You notice static electricity much more in winter (with clothes in a dryer, or taking a
