Induced EMF (electromotive force) is the voltage created in a conductor when it is exposed to a changing magnetic field. This can be caused by either a relative motion between the conductor and the magnetic field, or a change in the magnetic field itself.
Induced EMF is caused by a changing magnetic field, while a regular EMF is created by a direct current. Induced EMF is also temporary and only exists as long as the changing magnetic field is present, while a regular EMF can be sustained.
Faraday's Law of Induction states that the magnitude of the induced EMF in a circuit is directly proportional to the rate of change of the magnetic flux through the circuit. It is one of the fundamental laws of electromagnetism and is used to calculate the induced EMF in a given circuit.
Induced EMF is used in a variety of devices, such as generators, motors, and transformers. It is also used in technologies like wireless charging and induction stovetops. In addition, many electronic devices, such as smartphones and laptops, use induction to charge their batteries.
Exposure to high levels of induced EMF can have negative effects on the human body, such as headaches, fatigue, and nausea. It is important to follow safety guidelines and regulations when working with or near devices that produce high levels of induced EMF.
