Physics 201 Introduction to Electricity & Magnetism 

November 18 Ampere's & Biot Savart Laws  



Using Ampere's
Law to calculate B
A current flows down the center conducting cylinder (r<c) of a coaxial cable. A current of the same magnitude flows in the opposite direction along the outer conducting cylindrical shell (b < r < a). Determine the magnetic field everywhere.
Current flows along a thin, infinite sheet. The current per length along the sheet is j (A/m). What is the magnetic field above and below the sheet?
