Electromagnetism calculation help

SUMMARY

The discussion centers on the calculation of electric and magnetic fields required to accelerate an electron traveling in the positive x-direction while applying acceleration in the positive y-direction. The electric field is determined to point in the negative y-direction, while the direction of the magnetic field remains uncertain among participants. The uniqueness of the field direction choices is linked to the application of the Lorentz force, which governs the motion of charged particles in electromagnetic fields.

PREREQUISITES
  • Understanding of Lorentz force in electromagnetism
  • Familiarity with electric and magnetic field vector directions
  • Basic knowledge of particle motion in inertial frames
  • Concept of acceleration in electromagnetic contexts
NEXT STEPS
  • Study the Lorentz force equation and its implications for charged particles
  • Research the relationship between electric and magnetic fields in classical electromagnetism
  • Explore the uniqueness of field configurations in electromagnetic theory
  • Investigate the effects of combined electric and magnetic fields on particle trajectories
USEFUL FOR

Physics students, educators, and professionals in electromagnetism, particularly those focusing on charged particle dynamics and field interactions.

An electron is traveling in the +ve x-direction of an inertial frame T. An acceleration is given to the electron in the +ve y-direction with as large as magnitude as possible.

How do I specify directions of the electric and magnetic fields that will achieve this?

Why are the choice of field directions unique?

Surely the elctric field is pointing in the -ve y direction but not sure about the magnetic field.

I'm not sure though. Also have no clue why it would be unique!

I'm confused … is this two separate questions, a) for a purely electric field and b) for a purely magnetic field, or is it for one joint field? :confused:

If the former, then use the force! :biggrin:

(that's the Lorentz force, of course :wink:)​
