A) What is the magnitude and direction of the Magnetic field due to the superconductor at the location of the electron? B) What is the magnitude and direction of the force acting on the electron due to the superconductor's magnetic field?

The aurora is caused when electrons and protons, moving in the earth’s magnetic field of  ≈5.0×10^−5 T, collide with molecules of the atmosphere and cause them to glow. a.  What is the frequency of the circular orbit for an electron with speed 1.0×10^6 m/s? Assume that the electron moves in a plane perpendicular to the magnetic field. b.  What is the frequency of the circular orbit for a proton with speed 5.0×10^4 m/s?
