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.

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 It] and the outer conductor carries current I i in the opposite direction. The currents are distributed uniformly across the cross-sections of each conductorExpressing your answer in terms of the given symbols andpo. nd the magnitude IBI of the magnetic eld at a distance r R3. IBI = T abc sin(x 0x10 Submit Reset Reset All
