Subtler souls might prefer other Matusow tactics-like erasing the magnetic coding on their personal checks by running the code numbers under an electromagnet. "The effect," he says, "is that your checks will not be processed by the automatic sorting device. Someone at the bank will have to handle them personally. But after all, it's your money, and it should get the loving care it deserves...
...fields needed in atom smashers and in controlled fusion experiments, superconductors will eventually replace bulky elecromagnets in these areas. A 1-lb. superconducting magnet cooled by a 200-lb. refrigerating system and powered by a 6-volt battery can produce as intense a magnetic field as an iron-core electromagnet weighing several tons and requiring 50 kilowatts of power. Entire trains could be suspended above their roadbeds in strong magnetic fields produced by superconducting magnets, enabling them to travel more smoothly and with less friction at speeds over 300 m.p.h...
M.I.T. students seem to like this new acquisition, though as one said, "It looks like an exploding artichoke." Other wits want to turn it into a giant electromagnet. The university intends to keep a careful eye out for pranksters: the student body is famed for its technological wizardry, once welded a trolley to its tracks while it picked up passengers. The ironworkers who put up the Calder had a more practical approach. Said one: "It's no different than putting up a boiler. We like...
...Tests. If the object in Jimmy's eye had been of iron or steel, Colonel Passmore could have removed it with relative ease on his first try with an electromagnet. When he found that it was another material - almost certainly brass-all he could do was let the eye heal a little and hope to get at the object later. But there was grave danger that eye fluids would react with the metal and compel removal of the eye. Then Dr. Passmore remembered reading that Dr. Nathaniel Bronson II had begun work in New York on an ultrasound probe...
...current is sent through the coil for a fraction of a second, most of the pulling power switches in an instant from one end of the magnet to the other. A few flashlight batteries can supply enough juice-not nearly so much as would be needed by an equivalent electromagnet...
