Write a program to show a proton moving with constant velocity. At a set of observation locations fixed in space that

surround the path of the proton, continuously display the magnetic field made by the proton as it moves. Make the magnetic

field arrows cyan. Scale the arrows so that they don't overlap each other.

(a) What happens if you increase the speed of the proton?

(b) What happens if you change the sign of the moving particle to make it an electron?

(c) Does the magnetic field at one of your fixed observation locations change or stay constant?

(d) Add to your display the electric field made by the proton at your fixed observation locations. Make the electric field

arrows orange. Note that you need to scale the arrows representing electric field differently from the arrows used to

represent magnetic field, since these quantities have very different magnitudes and units.
