Electromagnetic devices are objects powered by electromagnetic fields, producing electricity or magnetized by electricity. They include motors, solenoids, generators, alternators, electromagnets, and electromagnetic coils. Solenoids are used in high-security time locks and electromagnetic bullet devices. Generators produce direct current while alternators produce alternating current. Electromagnetic devices are also used in security alarm sensors. The term […]
Electromagnetic flowmeters measure liquid flow through a pipe using conductivity and a magnetic field. They are non-invasive, low maintenance, and can be used in various industries. Proper grounding is necessary for accurate readings. An electromagnetic flowmeter, also known as a magmeter, is an instrument that measures the rate of flow of a liquid – or […]
Electromagnetic coupling occurs when an electromagnetic field in one wire induces an electric charge in another without physical contact. It is common in AC circuits and is the basis of transformers, motors, and communication devices. It can also cause interference, known as electromagnetic interference (EMI). Electromagnetic coupling is a phenomenon common to electrical wiring and […]
An electromagnetic generator uses magnetism and electricity to transform mechanical energy into electrical energy through electromagnetic induction. It can use renewable energy sources like wind and water power. Michael Faraday discovered this phenomenon in 1831, and the general design is still used today. The force used to spin the generator still requires an energy source, […]
