Using the Ampere-Turn Calculator to compare two coils
Coil Geometry: Select the geometry of your coil from the list. This is used to calculate the inductance and the energy stored. You can choose from single-layer solenoid, multi-layer solenoid and flat spiral coil forms.
Applied Voltage: Enter the voltage that will be applied to the coil. This is used in conjunction with the resistance of the conductor in order to calculate the current.
Number Of Turns: Enter the total number of turns.
Coil Length: Enter the coil length, measured as depicted in the diagram above.
Coil Diameter: Enter the coil diameter, measured as depicted in the diagram above.
Coil Depth: Enter the winding depth, as depicted in the diagram. This does not apply to a single-layer solenoid coil.
Conductor Length: This is used to calculate the resistance of the conductor.
Conductor Diameter: This is used to calculate the resistance of the conductor, and provides the scaling factor for comparing against a second coil.
Select Units: Select your preferred units of measurement for all the parameters.
