The class is about Electricity and Magnetism. The website wants exactly the perfect answer and in the same metric system units that are stated on the calculators that are on the picture for the question, if not, it'll mark it wrong.

Set 15 Problem 4 Cylindrical Conductors A pair of coaxial cylindrical conductors consists of a solid inner conductor of radius R1, surrounded by a cylindrical tube of inner radius R2 andouter radius R3. The inner conductor carries current /o and the outer conductor carries current /1 in the opposite direction. The currents are distributed uniformly across the cross-sections of each conductor. Expressing your answer in terms of the given symbols anduo, find the magnitude IBI of the magnetic field at a distance r R3. IBI = abc sin(x) Ox10 Submit Reset Reset All
