The net magnetic field created by the electrons within an atom is due to the field created by their _ motion.
Correct answer: B. Spin
- A. Orbital
- B. Spin
- C. Orbital & spin
- D. Orbital X spin
Explanation
Electrons have negative charge. When a charge spins, a magnetic field is created around it. Hence the spinning of electrons produces a magnetic dipole. If the majority of electrons in the atom spins in the same direction, a strong magnetic field is produced. The direction of the electron spin determines the direction of the magnetic field. (B)

About Atomic Spectra
Atoms emit or absorb light at specific wavelengths because electrons occupy quantized energy levels and change levels by absorbing or releasing photons. The topic covers emission and absorption spectra, spectral series, hydrogen’s line spectrum, energy-level transitions, and the relation between wavelength, frequency and photon energy.
