1. The problem statement, all variables and given/known data x and y are nonconducting cylindrical shells. Both cylindrical shells are surrounding long wires that are carrying current. the x shell out of the page and the y shell into the page. x radius has a charge per unit lenght = to +[tex]\lambda[/tex] y radius has a charge per unit lenght = to -[tex]\lambda[/tex] I need to calculate the maxwell stress tensor at a midway between x and y. (from the picture) 2. Relevant equations T^{ij} =[tex]\epsilon[/tex]_{o}(E_{i}E_{j}-[tex]\delta[/tex]_{ij}E^{2})+(1/[tex]\mu[/tex])(B_{i}B_{j}-[tex]\delta[/tex]_{ij}B^{2}) 3. The attempt at a solution How do I exactly found the i and j component of the magnetic and electric field?
