SUMMARY

J.J. Thomson established the relationship between electric and magnetic fields through a specific experiment involving cathode rays. He created perpendicular electric and magnetic fields and utilized X-rays to eject electrons from an oil drop. This method allowed him to derive the relation between the electric field (E) and magnetic field (B) in his experiments, which is expressed as e/m = 1/76 x 10,000,000,000 c/g. This foundational work contributed significantly to the understanding of electron behavior in fields.

PREREQUISITES
  • Understanding of electric and magnetic fields
  • Familiarity with cathode ray experiments
  • Knowledge of Thomson's contributions to physics
  • Basic principles of electromagnetism
NEXT STEPS
  • Research J.J. Thomson's cathode ray experiment in detail
  • Study the principles of electromagnetism and their applications
  • Learn about the behavior of electrons in electric and magnetic fields
  • Explore the historical context of Thomson's experiments and their impact on modern physics
USEFUL FOR

Physics students, educators, and anyone interested in the historical experiments that shaped modern electromagnetic theory.

i need to know how does thompsonfind out relation between electric field &
magnetic field.(in cathodi lamps)

e/m=1/76 x 10,00000000 c/g ??

tnx
bye
 
Physics news on Phys.org
actualy he didn't found iot in the cathode ray experiment ,it was another experiment conducted by him to find it.
In the experiment he created electric and magnetic field perpendiculer to each other then with the help of x-ray he knocked the electrons out of the oil drop and then by using the electric and magnetic fields simultaneous he derived the relation.
