Select the geometry of your coil from the list.

Calculating inductance of flat sheet of copper.

If dimension unit is mils then dimension is 0 0254. Resources eis inductance calculator. 1 inch 0 0254m 2 54cm 25 4mm. Enter the coil diameter measured as depicted in the diagram above.

Using the coil inductance calculator. μr μ r relative permeability. D d wire diameter. The inductance of a flat or ribbon wire or a track on a pcb can be calculated with the following equation.

You can choose from single layer solenoid multi layer solenoid and flat spiral coil forms. Where l is the length in cm w is the width in cm t is the thickness in cm pcb copper 1 oz ft2 0 035mm. On the contrary wires have a certain amount of resistance that increases with length and decreases with diameter. D d loop diameter.

This formula applies at low frequencies 30mhz using enameled copper wire. A flat spiral coil is a type of an air core inductor usually incorporated in the primary of a tesla generator rfid tag and proximity detectors. We generally associate inductance with a loop or coil of wire. This calculator uses javascript and will function in most modern browsers.

ρ is the resistivity of the conductor in ω m. L inductance u r relative permeability of the core material air 1 turns number of turns on the coil area the cross sectional area of the core in square meters including some of the coil as shown in the diagram length length of the coil in meters. L is the length in metres. Inductance of the conductor μh ell.

Width of the conductor mm t. Strap inductance 0 2 l in 2 l w t 0 223 w t l 0 5 dimension where l length w width t thickness if dimension unit is mm then dimension 1. Thickness of the conductor mm. Length of the conductor mm w.

Lcoil n 2μ0μr d 2 ln 8d d 2 l c o i l n 2 μ 0 μ r d 2 l n 8 d d 2 where. However even a straight piece of wire or your electrode has some self inductance this can be important if you are dealing with low impedances 1 ohm at high frequencies 10khz. Some people call it magnet wire. If we wind a wire into a coil it obviously creates inductance but even a straight piece of wire or a component lead has some parasitic inductance caused by the magnetic field that it creates.

Lcoil l c o i l inductance of the coil in henries h n 2 n 2 number of turns. For more information see about our calculators. Even a single straight piece of wire has some inductance. Copper is not a perfect conductor.

Enter the coil length measured as depicted in the diagram above.
