What is the Lagrangian L=T-V for a conical pendulum? This is a pendulum with length l and bob mass m that rotates in a horizontal circle with theta (angle l makes with z axis) and phi(dot) (angular velocity-omega) are constant (cylindrical coordinate system).

1) a magnetic field on one side of an infinite plane of uniform surface current K=K*j(hat) is found to be
B= 1/4* mu(nought)*K*i(hat)
What is the magnetic field below the plane (accounting for the discontinuity across the plane)
