A +7.00 μC point charge is moving at a constant 7.50 ×106m/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 vector B? it produces at the following points.
x=0.500m,y=0, z=0
x=0, y=?0.500m, z=0
x=0, y=0, z=+0.500m
x=0, y=?0.500m, z=+0.500m
