1. A student uses a coil of radius 14 cm with 90 windings.a) Calculate the expected slope for a plot of magnetic field vs current in this coil.b) She performs the lab and measures a slope of 4.2 ́ 10-4 T/A. Based on this slope, what valuedoes she calculate for μo ?c) Calculate the percent error between her measured value of μo and the theoretical value.
