A `+6muC` point charge is moving at a constant velocity of `8xx10^6 ms^-1` 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 it produces at the following points?
(a) `x=0.500m, y=0, z=0,` and (b) `x=0, y=-0.500m, z=0`.

Explanation

To solve the problem of finding the magnetic field produced by a moving point charge at two specified points, we will use the Biot-Savart Law. Here’s a step-by-step solution:

### Given Data:
- Charge, \( q = +6 \, \mu C = 6 \times 10^{-6} \, C \)
- Velocity, \( v = 8 \times 10^6 \, m/s \) (in the +y direction)
- Points to evaluate:
- Point A: \( (x = 0.5 \, m, y = 0, z = 0) \)
- Point B: \( (x = 0, y = -0.5 \, m, z = 0) \)
