Calculating length of wire in existing electromagnet

Calculating length of wire in existing electromagnet


I would like to ask for little help in calculating the length of wire in the existing electromagnet (bought from the shop).
I know that bought electromagnet is for DC, 24[V], 1.3[A], 33[W]. Diameter of the wire is 0.52mm. I kindly ask for help.

Thank you.


RE: Calculating length of wire in existing electromagnet

If you know the bare wire diameter and the total resistance then assuming the resistivity is close to the standard 100% copper 5.4E-08 ohm-meter you can easily calculate the length of the wire.
