Hydrogen Atom (this is not chemistry)

Click For Summary
SUMMARY

The discussion focuses on calculating the magnetic field at a proton due to an electron in a simplistic hydrogen atom model. The relevant formula for the magnetic field, B, is B = μ₀ * I / (2πR), where I is the current generated by the electron's motion. The user initially attempted to derive the current using the charge of the electron and the period of its orbit but arrived at an incorrect value. The correct approach involves using the formula for B at the center of a current loop, which is essential for accurate calculations in this context.

PREREQUISITES
  • Understanding of electromagnetic theory, specifically magnetic fields generated by moving charges.
  • Familiarity with the concept of current (I) and its calculation from charge and time.
  • Knowledge of circular motion and angular frequency in physics.
  • Proficiency in using the permeability of free space (μ₀) in magnetic field calculations.
NEXT STEPS
  • Study the derivation and application of the magnetic field formula for a current loop.
  • Explore the concept of angular frequency and its relationship to circular motion.
  • Learn about the implications of the Biot-Savart Law in calculating magnetic fields.
  • Investigate the differences between magnetic field calculations for straight wires versus loops.
USEFUL FOR

Students of physics, particularly those studying electromagnetism, as well as educators seeking to clarify concepts related to magnetic fields in atomic models.

Homework Statement


A rather simplistic model of the hydrogen atom has a single electron revolving around a nuclear proton with an orbital radius of 5.40E-9 m at a speed of 5.00E+6 m/s. Determine the magnetic field at the proton due to the electron.

Homework Equations



B=u0*I/2piR

I=Q/t

V/R=2pif

f=1/T


The Attempt at a Solution



I tried to do V/R to get the angular frequency, converted to frequency then period. Take the period and divide it by the charge of an electrons. After putting the current in the formula, I got 0.000873 T, but it's wrong... any suggestions?

Your formula for B is for a long straight wire.
Use the formula for B at the center of a current loop.
