A toroid having a square cross section, 0.43 cm long on a side, with a 0.51 cm inner radius has 298.00 turns and carries a current of 2.30 A. It is made of a square solenoid bent into a donut shape. What is the magnetic field inside the toroid at the outer radius

The chemical reactions lab we did is typically called a "copper plating lab,  because the acid solution cleaned the pennies and made the copper look shinier;   the acid solution cleaned the paperclips and made them look like pennies;   &   the copper from the pennies was removed, and then added to the paperclips.
