Because motors are so important to everyday activities and because they are, in essence, a generator working in reverse, we'll examine them more closely in the next section.Electric Motors Behold the large horseshoe electromagnet used by English physicist and chemist Michael Faraday, around 1830...
This same system can work in reverse, which is what happens in a basic pressure detector. Pressure fluctuations move the cone back and forth, which pushes and pulls the attached electromagnet. When the brain registers a significant current flowing from this device, it knows that something has ca...
a curious duality ensues: We take electricity for granted one second and gawk at its power the next. More than two and a half centuries have passed sinceBenjamin Franklinand others proved lightning was a form of electricity, but it's still hard not to flinch when...

Worldwide, hydropower plants produce about 24 percent of the world's electricity and supply more than 1 billion people with power. The world's hydropower plants output a combined total of 675,000 megawatts, the energy equivalent of 3.6 billion barrels of oil, according to the National Renewable...
They essentially operate as the reverse of a loudspeaker, using a diaphragm, voice coil, and magnet to turn a sound wave into an audio signal. Dynamic mics are typically the first choice for onstage miking. Condenser Mics have thinner diaphragms with an eclectically charged backplate to ...

If you hook the battery leads of the motor up to a battery, the axle will spin. If you reverse the leads, it will spin in the opposite direction. The nylon end cap is held in place by two tabs. Inside the end cap, the motor's brushes transfer power from the battery to the ...
Two separate PCR reactions are performed to detect mutations. In the presence of a mutation, the use of a primer complementary to the mutated DNA and a universal reverse primer in the reaction will result in a band in the gel electrophoresis, while in the absence of a mutation, the band ...
