Four Rotating Magnets Run Clock.<\/strong><\/p>\n

NO MATTER how closely you listen, you can’t hear this clock tick because four rotating magnets have replaced the old gears, making the clock “tickless.” The mechanism of this new timepiece, shown below, is made up of four magnetic fields. One rotates every second; one each minute; the third each hour; and the fourth operates the hour hand at the rate of one revolution every twelve hours.<\/p>\n

The new clock must be set face up on a table or support because the mechanism doesn’t function properly when hung on a wall or placed on the mantel.\n<\/p>\n<\/blockquote>\n
