Question

1. A mass spectrometer uses a 1 T magnet with a very uniform field pointing in the vertical direction,

upward. A beam of particles which are heavy metal ions (charge +1e) enters the field region in the

horizontal direction.

a. Is the beam deflected to the left or right?

b. If the beam has a mix of iron (A = 55), cobalt (A=56), and nickel (A=57), all having the same

velocity, with the indicated approximate atomic weights, which one is deflected the most? !!!!!

2. A radio wave is generated by an antenna which is essentially a vertical metal rod with electric charges

oscillating along its length. At a distance of several kilometers from the antenna you measure the

magnetic field component of the radio wave. In which direction does it oscillate?
