A 100.0-m-long, 1.20-mm-diameter copper wire (resistivity 1.70*1082m) is shaped into a circular coil that consists of 150 identical turns. The coil is then connected to the terminals of a 9.00-V-battery that has internal resistance of 1.50 12. Calculate the strength of the magnetic field (due to the current running through the coil) at the center of the coil.

An 80 cm long wire is made by welding a 1.8 mm diameter, 20 cm long copper wire to a 1.8 mm diameter, 60 cm long iron wire at normal room temperature (20 ∘C). When two wires are connected end to end, their resistances add together. The resistivity of copper is 1.68×10−8Ωm and the of iron is 1.00×10−7Ωm. The temperature coefficients are: copper = 0.0039/∘C and iron = 0.0050/∘C. What is the resistance of the copper section of wire?
