Coil Physical Properties Calculator

See our other Electronics Calculators.

Both inductors and electromagnets consist of wires wound around a bobbin or core form.  In designing and constructing the coil it becomes necessary to estimate the cross sectional area, and resistance of the coil. 

This calculator estimates the physical properties of a coil such as resistance, total length of wire needed and number of windings, give the wire diameter, and bobbin length.  The calculator assumes copper wire for resistance and voltage calculations.
