What is magnetic induction?
Magnetic induction is a physical phenomenon based on the interaction of magnetic fields with electrical conductors. It describes the generation of an electric voltage or current in a conductor when the magnetic field around the conductor changes.
Magnetic induction is based on the laws of the electromagnetic induction principle, which was first discovered by the scientist Michael Faraday in the 19th century. It states that a change in magnetic flux through a loop of conductor material induces an electromotive force (EMF) in the loop.
How does magnetic induction work?
Magnetic flux is a measure of the strength of the magnetic field that permeates a surface. It is measured in units of Weber (Wb). When the magnetic flux in a loop changes, there is a change in the magnetic flux density, which in turn causes an induced EMF in the loop. This EMF can be used to generate an electric current.
The magnitude of the induced EMF depends on the speed of the change in magnetic flux: The faster the change, the greater the induced EMF. This is described by Faraday's law, which states that the induced EMF is proportional to the rate of change of the magnetic flux.
What are the applications of magnetic induction?
Magnetic induction is of great importance in various areas of physics and technology. In electrical engineering and electronics, for example, it plays a role in the operation of generators and transformers. In generators, mechanical energy is converted into electrical energy by rotating a magnetic field relative to a coil, creating an induced EMF. Transformers use magnetic induction to transform and transmit AC voltages.
Furthermore, magnetic induction is used in magnetometry as well as in magnetic resonance imaging (MRI).
