In the simulation below, select the Electromagnet tab, and make sure you select the Show Field Meter box. For a coil of 3 turns and a battery voltage of 2 volts, use Ampere's Law to estimate the current flowing in the coil. You can assume that the coil has a diameter of 2 cm. For the permeability constant, use μ₀ = 1.26 × 10⁻⁶ H/m. Note, the field meter measure the field in Gauss, and 1 Gauss = 10⁻⁴ Tesla.
