☑ Calculate Inductance Comsol

The magnetic field b exists within and outside of the wire. Voltage across a closed path in terms of the electric field multiply each obtained value of e phi by the perimeter length of the corresponding loop the induced voltage in each loop is.

The problem was solved as a magneto static problem.

Calculate inductance comsol. 12687 the mutual inductance and induced currents between a single turn primary and twenty turn secondary coil in a concentric coplanar arrangement is computed using a frequency domain model. Total magnetic energy is wm10534e 4 j and inductance of coil is l526uh. With the tools provided by the acdc module in comsol multiphysics you can model and design an inductor in a straightforward yet accurate way as well as calculate the device characteristics your application demands.

Within the wire it increases linearly outwards from the centerline. Inductance of coil is calculated from total magnetic energy created by current passing through the coil using the following formula. Self inductance and mutual inductance of a single conductor and a homogenized helical coil application id.

The basic physical principles of an inductor. The inductance l is defined in terms of the current i flowing through the system and wm the magnetic energy density is proportional to b2. The arrangement is then modeled in an ac state to compute the induced currents in the secondary coil.

However you can still calculate the mutual inductance by analyzing the total magnetic flux and comparing it with analytic results.
