(II) A straight stream of protons passes a given point in space at a rate of 2.5 × 109 protons/s. What magnetic field do they produce 2.0 m from the beam?
The stream of proton constitutes a current, whose magnitude is found by multiplying the proton rate times the charge of proton. Then use Eq. 28-1 to calculate the magnetic field.
