5mm copper wire on a clear acrylic base support side-by-side comparison of how loop count multiplies the on-axis magnetic field at fixed current

the shared mass isolating volume and density as the distinguishing variables across metals and polymers

Wider 70 x 20 x 8mm cross-section on this Alnico bar pair gives a broader pole face than typical bar magnets

Faraday's Butterfly Net Electricity & Magnetism_Circuits mechanical-advantageDemonstrates that charge resides only on the outer surface of a conductor by inverting the charged net inside out and showing the charge transferring to the new outside layer.
