Question:

A +6.00-μC point charge is moving at a constant 8.00 X 106 m/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:
(a) x = 0.500 m. 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?
