5. An electron orbiting an atomic nucleus forms its own kind of current loop. For a hydrogen atom in the lowest energy
state, a single electron orbits the nucleus with a radius of 52.9 pm (5.29 × 10-11 nm) and a speed of about 2.2 x 106
m/s.

(a) Conventional current measures the amount of charge passing a certain point per unit time: I =
In this
case, Qis the electron charge, and At is the time it takes the electron to complete one full orbit. Using this
information, what is the magnitude of the conventional current in the hydrogen atom?
Answer: I = 1.05 mA.
(b) What is the magnetic field (both magnitude and direction) at a distance of 5.29 nm along the axis of the atom,
at the point indicated?
Answer: -1.25 × 10-5 T 2
