A cylindrical volume of space contains a uniform magnetic field of magnitude \(0.12 \mathrm{~T}\) but unknown direction. If the dimensions of the cylindrical volume are length \(\ell=0.060 \mathrm{~m}\) and radius \(R=0.040 \mathrm{~m}\), how much \(\mathrm{mag}\) netic potential energy is stored in the field?
