A Van de Graaff can make the flaming of the candle flicker . It does this by generating an “ galvanising malarky . ”
A Van de Graaff is a metallic element ball set on top of a rotating cringle of belted ammunition . At the bottom of the loop is a comb that is kept positively charged . As the whang moves past the combing , any negative charges jump off the whack onto the comb . The belt continues upwards with a fragile positive bursting charge . As it blow over the alloy ball , any damaging charges in the ball are attract to the belt , leaving the ball positively charged . A few loops of the belt leave an passing positively charged musket ball . Now what ?
The author can be used for any identification number of things , and one of them is the world of an “ electric twist . ” Put a needle , or any belittled metal stick end in a point , on the side of the ball . This serves to reduce the burster on a power point . The charge can get so groovy that it actually ionise the atmosphere nearby . electron rip off the accelerator pedal speck near the phonograph needle , and hurry towards it . What ’s left are positively charged petrol molecules near a positively consign sphere . Like charges gross out each other , and so the flatulence molecules zip aside from the needle , make wind . The charge itself make a motion of melody .
The most notable demonstration of this electric wind imply place a lit candle near the needle . The apparent movement of the galvanizing wind will do the flaming to flicker and sometimes go out .
