Take a look at the following sketch representing a rotating neutron star that is beaming radiation as a pulsar. "a" represents a bar magnet - something we are familiar with - with a north and south magnetic pole - with the magnetic field emanating from it. this field is indicated by the dashed curving lines close to the neutron star "c" and the solid lines with arrows farther away "d". the spiraling of electrons in the magnetic field is shown at "b". which of the following choices correctly ranks the source of the highest to lowest energy radiation.
