A point charge Q moves along the +X{“version”:”1.1″,”math”:”+X”} direction with a speed of 370 m/s. A point P is on the y-axis at y = +80 mm. The magnetic field at P as the charge moves through the origin is equal to -0.80 μT k^. {“version”:”1.1″,”math”:”-0.80 μT k^. ”}When the charge is at x = +40 mm, what is the magnitude of the magnetic field at the point P?
