B-Field of an Infinite Sheet of current

In this video, we find the magnetic field for an infinite sheet of current with linear current density K. We make a symmetry argument to figure out what the magnetic field looks like above and below the magnetic sheet of current, and then apply Ampere's Law to find out the magnetic field.
