Suppose we have the following design dimensions:

A circular loop made with copper wiring with $45$ turns and radius r$=3\mathrm{.}5$cm

A neodymium disk magnet with magnetic field strength B$=0\mathrm{.}45$T at the copper loop

A current of I$=2\mathrm{.}5$A through the copper loop

$20-$Gauge copper wiring with mass density ~$4\mathrm{.}65$ g$/$m in length, giving us a loop mass of $0\mathrm{.}04599315$ kg
