In the bohr model of the hydrogen atom, the electron moves in a circular orbit of radius 5.3× 10 −11 m with speed 2.2× 10 6 m/s . part a according to this model, what is the magnetic field at the center of a hydrogen atom due to the motion of the electron? hint: determine the average current of the orbiting electron. express your answer in tesla. b b = nothing t submitrequest answer return to assignment provide feedback

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
