The in situ magnetic measurements were achieved by our homemade two-coil mutual inductance (MI) devices, composed of a drive coil and a pick-up coil as described in ref. [15] [16] [17][18]. Both5 Best Free Inductance Calculator For Windows Coil32. Coil32 is a free inductance calculator for Windows. Both installer and portable versions of this software are available on its website. Using this free inductance calculator, you can calculate inductance of the following inductors: One turn loop coil. One-layer coil with close winding. One-layer coil with winding pitch.Comparison of Measurement Methods for Piston and LVIT consists of a core of paramagnetic and electric conductor material (commonly aluminum) that moves inside a coil. The displacement of the core causes an opposite magnetic field that changes coil inductance (Meydan & Healey, 1992) (Seco, Martn, Jimnez, & Caldern, 2005) (Alciatore & Histand, 2012). A conditioning module, which also

The distance between ferrite plate and aluminum shield is set to 20 mm to reduce the eddy current loss in the aluminum shield. The vertical distance between transmitter and receiver (h) is maintained at 140 mm to minimize inductance variations due to their relative position.
