A beam consisting of 8.22x10^16 electrons/sec passes through a region of vacuum. A) What magnetic field would be measured 1.50cm away from the center of the beam? B) A similar beam, this time made up of "alpha particles" with the same number of particles/sec as the electron beam in (A), now passes through the vacuum. What magnetic field strength will be measured at the same distance of 1.50cm?
