Can you hear me? Well, now you will certainly be able to! Hearing aids use electromagnetic induction by first allowing the microphone to pick up electrical signals (sounds) from the environment. The amplifier then, well, amplifies the sounds, and the receiver changes the electrical signals to sounds and sends it to the brain for processing. In order for this all to work, you must use a battery, which si the basis for the relatively simple invention.

ELECTROMAGNETIC INDUCTION HEATING GRILL
Missing a device to create some underappreciated grilled cheese? Well have we got the invention for you! The EMIHG contains various parts that use electromagnetic induction in order to work, including a casing body and a micro crystal plate that connect to the control device, which plugs into the wall and runs the machine. The control device starts the process, where the energy moves quickly from outer casing, to the first micro crystal plate, and then to the second casing and microcrystal plate. The quick speed in which it moves allows for easy 15 min dinners, and saves money for all consumers by using less electricity. Be sure to pick up your EMIHG today!

Moving Coil Microphones
Singer? Stand up comedian? Avid bingo player? Then this microphone is for you! Our moving coil microphones work all because a movable induction coil, in the magnetic field of a magnet, is connected to the diaphragm, a part of the mic. When sound enters through the microphone, the sound waves moves the diaphragm. When the diaphragm is moved, the coil moves in the magnetic field, producing a current in the coil through electromagnetic induction.
