2. What is the eddy current?
Induced E.M.F, or electromotive force, is not a force in the traditional sense. It is a measure of the voltage produced by the changing magnetic field in a circuit. However, it can cause a force on electric charges, which is why it is often referred to as a "force".
Eddy currents are circular electric currents that are induced in a conductive material when it is exposed to a changing magnetic field. These currents flow in a direction that opposes the change in the magnetic field, and they can cause a dissipation of energy in the material.
Eddy currents are a result of the induced E.M.F in a conductive material. When the magnetic field changes, it induces a voltage in the material, which in turn creates eddy currents. This phenomenon is known as electromagnetic induction.
Understanding eddy currents is crucial in various industries, including power generation, transportation, and manufacturing. It is used in devices such as transformers and electric motors, and it is also a factor to consider in the design of magnetic shielding to reduce interference.
Eddy currents can be minimized or controlled by using materials with high electrical resistivity, such as laminated cores in transformers. Other methods include using magnetic shielding or altering the shape and size of conductive materials to reduce the surface area for eddy current flow.
