“No. 22” magnetic wire usually refers to the specification of its wire diameter, not its length. Magnetic wire of different specifications have different diameters, but their length is not determined by the specifications.

Generally speaking, the larger the size of the magnetic wire, the smaller the diameter. Therefore, a No. 22 magnetic wire with the same length and weight is shorter than a thinner enameled wire.

If you want to know how long a pound of 22 gauge magnetic wire is, you need to know the wire’s density, or wire density (i.e., the weight of the wire per unit length). You can then use this density to calculate the length. In general, the linear density of 22 magnetic wire of different brands and materials may be different, so the accurate length requires specific linear density data.
