Calculating inductance of flat sheet of copper. For more information see about our calculators. This formula applies at low frequencies 30mhz using enameled copper wire. Enter the coil length measured as depicted in the diagram above. On the contrary wires have a certain amount of resistance that increases with length and decreases with diameter.

D d loop diameter. Thickness of the conductor mm. We generally associate inductance with a loop or coil of wire. Enter the coil diameter measured as depicted in the diagram above.

The inductance of a flat or ribbon wire or a track on a pcb can be calculated with the following equation. The dc resistance of a conductor is calculated using the equation where. Length of the conductor mm w. μr μ r relative permeability.

Copper is not a perfect conductor. 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. 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. Inductance of the conductor μh ell.

Some people call it magnet wire. D d wire diameter. 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. ρ is the resistivity of the conductor in ω m.

Using the coil inductance calculator. 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. 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. Width of the conductor mm t.

If dimension unit is mils then dimension is 0 0254. 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. One formula for inductance is as follows.

μ0 μ 0 permeability of free space 4π 10 7. 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. 1 inch 0 0254m 2 54cm 25 4mm. You can choose from single layer solenoid multi layer solenoid and flat spiral coil forms.
