use the biot savart to compute the magnetic field at the center of a matalic ring. the ring has a radius of 10^-6 m and is connected to two infinite wires. the current in the wires is 1 ampere. the ring is lying in the [x,y,z=0] plane. the first wire is attached to the ring at x=0,y=10^-6 m, z=0 and the current flows in the +y direction. the second wire is attached to the ring at x=0,y=-10^-6 m, z=0 and the current flows in the +y direction. compute the magnetic field at the center of the ring [x=0,y=0,z=0]. indicate the value of the magnetic field and direction?
