Calculating inductance of flat sheet of copper.

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. Thickness of the conductor mm. 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.

Even a single straight piece of wire has some inductance. 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. Copper is not a perfect conductor. Some people call it magnet wire.

μr μ r relative permeability. We generally associate inductance with a loop or coil of wire. Select the geometry of your coil from the list. The inductance of a flat or ribbon wire or a track on a pcb can be calculated with the following equation.

ρ is the resistivity of the conductor in ω m. 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. Resources eis inductance calculator. Using the coil inductance calculator.

Enter the coil length measured as depicted in the diagram above. 1 inch 0 0254m 2 54cm 25 4mm. μ0 μ 0 permeability of free space 4π 10 7. L is the length in metres.

Enter the coil diameter 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. If dimension unit is mils then dimension is 0 0254. This calculator uses javascript and will function in most modern browsers.

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. Inductance of the conductor μh ell. D d wire diameter. D d loop diameter.
