The magnet moving past an object will produce Eddy currents in the object if the object is a conductor.
- Eddy currents are electrical currents induced in closed loops within a conductor.
- For this to happen the conductor has to be in the presence of a magnetic field.
- A moving conductor in a stationary field or a stationary conductor in a varying field will induce an emf called the Eddy current.
- This current flows perpendicular to the magnetic field plane.
- Therefore, a magnetic field and a good conduction material are important factors for the generation of Eddy currents.
