What is eddy current?
Eddy currents are circular electric currents induced in conductive materials when subjected to a changing magnetic field. These currents flow in closed loops, circulating within the material, and are responsible for various effects, including energy dissipation, heating, and electromagnetic damping.
How to Calculate Depth of Permanent Magnet?
Depth of Permanent Magnet calculator uses Permanent Magnet Depth = Metal Disc Thickness*(Eddy Current Path Resistance*Permanent Magnet Width)/Disc Material Resistivity to calculate the Permanent Magnet Depth, The Depth of Permanent Magnet formula is defined as the distance within a material at which the magnetic field strength generated by the magnet falls to a certain fraction of its maximum strength. Permanent Magnet Depth is denoted by D symbol.
How to calculate Depth of Permanent Magnet using this online calculator? To use this online calculator for Depth of Permanent Magnet, enter Metal Disc Thickness (T), Eddy Current Path Resistance (Re), Permanent Magnet Width (B) & Disc Material Resistivity (ρ) and hit the calculate button. Here is how the Depth of Permanent Magnet calculation can be explained with given input values -> 2.15 = 0.26*(0.02*4.3)/0.2.
