A+6.00 μc point charge is moving at a constant 9.00 ×10^6m/s in the + y-direction, relative to a reference frame.
at the instant when the point charge is at the origin of this reference frame, what is the magnetic field b it produces at the following points?

a) x=0.500m, y=0, z=0
b) x=0, y=-0.500m, z=0
c) x=0, y=0, z=+0.500m
d) x=0, y=-0.500m, z=+0.500m
