Example text
In applications where the current and voltage remain low to moderate, electronic semiconductor switches, which have no moving parts, offer better performance and reliability than relays. In a DC motor, you connect a source of electricity to a set of coils that produce small-scale, but nevertheless powerful, magnetic fields. The attraction of opposite poles, and the repulsion of like poles, is manipulated so that a constant torque (rotational force) results inside the device. As the coil current increases, so does the torque that the motor can produce, and so does the energy it takes to operate the motor at a constant speed.
When you do that, you place a short circuit between the two points under test.
In theory, you can, but don’t try it! You’ll short out your house wiring, expose yourself to the risk of electrocution, expose your house to the risk of fire, and probably cause a fuse to blow or a circuit breaker to open, cutting power to the device anyway. Some buildings lack proper fuses or breakers, and shorting out one of those systems can lead quickly to disaster. If you want to build a safe AC electromagnet, my book Electricity Experiments You Can Do at Home (McGraw-Hill, 2010) offers instructions for doing it.
