...have weak floors, groove hopper). It is connected to a control rod, or "stylus arm" which wiggles along with its maneuverings. This stylus arm is in turn either connected to a crystal against which it vibrates, causing voltages to appear across it, or it in some way moves a coil through a magnetic field, cutting lines of force, and again causing voltages to arise...
Anytime you move a magnet in the close proximity of a coiled wire (or vice versa) you cause a current to flow through the coil. In the stereo cartridge we can either attach a magnet to the stylus arm and hold two coils stationary in the body of the device, or we can wind two coils onto the arm in different directions and mount a stationary magnet in the body. Either way (one is called "moving magnet", the other "moving coil" for obcious reasons), when the needle does its mazurka in the groove the stylus arms follows, and the groove...
...commercials was that they had been made with so much more imagination, humor, photographic skill and musical talent than the programs they were designed to interrupt. The cinematography in a Prell shampoo blurb was visual poetry as it showed, with crystalline acuity, each gob of goo sinking into each coil of hair. There was the pathos of Willy Loman in a Metrecal pitch called the Lonely Man (commercials have titles these days), which showed a forlorn, overweight figure trudging through Central Park on a cheerless winter day while a narrator spoke of blubber in tones of quiet reasonableness...
...such supermagnet has yet been built. For one thing, it will surely prove to be extremely violent: its field of 100,000 gauss will exert a force of six tons per sq. in. at the end of the coil. Another difficulty is that the coil will have to be kept near absolute zero, presumably by bathing it in liquid helium, whose high volatility makes it a nightmare to handle...
...vulgar, powder burns on a lot that is neurotic or just human. They go at each other as a way of going at many things else: they are mamma and papa, or mother and son, or lover and mistress, or brother and sister, or monsieur and madame; they coil round each other constantly like flowers, teenagers or snakes...
