Are Electric and Magnetic Fields Zero for a Moving Charged Particle?

Click For Summary

Homework Help Overview

The discussion revolves around the behavior of electric and magnetic fields in relation to a charged particle moving at constant velocity in a straight line. Participants are exploring the implications of this scenario on the forces acting on the particle.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are questioning whether electric and magnetic fields can be zero for a moving charged particle and discussing the conditions under which forces may or may not act on the particle. There are inquiries about the relationship between velocity, acceleration, and the resulting forces.

Discussion Status

The discussion is active, with participants exploring various interpretations of the conditions for constant velocity and the presence of forces. Some guidance has been offered regarding the balance of forces, but no consensus has been reached.

Contextual Notes

There are references to specific equations and conditions that may affect the understanding of forces acting on the particle, including the potential presence of electric and magnetic fields that could balance each other out.

If a charged particle moves at a constant velocity in a straight line through a region of space, is the electric field and/or magnetic field in the region zero?
 
Physics news on Phys.org
If a charged particle moves at constant velocity, in a straight line, what is its acceleration? What, then is the force on it? What does that tell you about the electric and magnetic forces and fields?
 
So, no forces?
 
wait, according to the equation F=qvBsin theta ...can't there still be a magnetic force?
 
oh wait nvm i got it lol

what is another condition for constant velocity or it going in the straight line. if there's an electric field pulling it up and a magnetic field pulling it down...
 
To sum it up,either both are absent,or present,but with perfectly balanced effects adding (as vectors) to zero.
