Uses or Simple Applications of Electromagnetism in Technology and Life

 

telephone uses electromagnet

Electromagnet, device consisting of a core of magnetic material surrounded by a coil through which an electric current is passed to magnetize the core. An electromagnet is used wherever controllable magnets are required, as in contrivances in which the magnetic flux . Jan 13,  · Electromagnets are also used extensively when it comes to musical equipment. These include loudspeakers, earphones, electric bells, and magnetic recording and . Every appliance that has a motor in it uses electromagnets. The only appliance that I can think of right now that does not use electromagnets in it is a toaster and a bus. I WANT A COOKIE AND A.

A hand-held portable speaker hooked up to your new smartphone contains a small electromagnet or voice coil telephone uses electromagnet of it, as do all devices with speakers, telephone uses electromagnet. The electromagnet translates the electrical current into sounds you telephone uses electromagnet hear by vibrating the paper cone or diaphragm.

The current in the electromagnet controls these vibrations that allow you to hear your favorite songs. Electrical devices that require changing currents use electromagnets. Electromagnets typically consist of copper wire arranged in a coil around a magnetic metal like iron. An electrical current passes through the wire and creates a magnetic field when juiced with power, telephone uses electromagnet, centering the magnetic flux on the iron core.

Once the current shuts down, the telephone uses electromagnet ceases to magnetize. By increasing or decreasing the current through the coiled wire, it strengthens or weakens the magnetic field.

The controlled electrical current increases the applications of the electromagnet compared with a static and permanent magnet. Electromagnets help maglev trains function and move, but they also help create the magnetic field of a medical magnetic resonance imager to capture images inside the body not viewable by X-ray machines or other means.

To create the binary code, 0 or 1, the read-write head simply changes direction, driven by the electromagnet. The hard drive uses the same head to interpret the information written to the disk, telephone uses electromagnet. The solenoid valve inside washing machines that turns water off or on is a type of electromagnet. Garbage disposals, telephone uses electromagnet, microwave ovens and induction cooktops all have electromagnets inside them, telephone uses electromagnet.

Electric power lines with large gray canisters have electromagnets inside these transformers to step-down the high-voltage current from the power line to a residence or business. The telephone uses electromagnet inside the gray transformer makes it possible to transfer the electrical current, which is typically a much higher voltage in the power distribution grid. The site receiving electricity gets it at a lower voltage.

As a journalist and editor for several years, Laurie Brenner has covered many topics in her writings, but science is one of her first loves. Her stint as Manager of the California State Mining and Mineral Museum in California's gold country served to deepen her interest in science which she now fulfills by writing for online science websites.

Brenner is also a published sci-fi author. She graduated from San Diego's Coleman College in TL;DR Too Long; Didn't Read Some everyday devices that have electromagnets inside them include: Microphones, speakers, headphones, telephones and loudspeakers Electric motors and generators Doorbells and electric buzzers Computer hard drives Multiple household appliances.

Cell Phones and Electromagnetic Radiation. What Kind of Harm Can Cell Phone Radiation Cause? There’s no argument that cell phones emit an electromagnetic field, which is a form of microwave radiation, that enters the brain when the cell phone is held against the ear, and there’s good research showing that the field does affect brain function.
