A wire coil is often used to generate magnetic fields, and it is important to know how many complete turns (‘loops’) of wire are in the coil. Copper wire with circular cross-sectional area 0.70 mm2 is used to make a coil by being wound around a cylinder of diameter 40 cm. After winding the coil, it is measured to have a total resistance of 3.7Ω. How many turns of wire are on the spool?
resistivity of copper: 1.72 x 10-8 Ωm
