Discussion Overview

The discussion centers around the equation for the force exerted on a charged particle, specifically a beta particle, moving perpendicularly through a magnetic field. The focus includes the Lorentz force equation and the vector cross product involved in determining the force's direction.

Discussion Character

  • Technical explanation, Conceptual clarification

Main Points Raised

  • One participant inquires about the existence of an equation for the force on a charged particle in a magnetic field.
  • Another participant references the Lorentz force equation as the relevant equation and suggests consulting Wikipedia or standard textbooks for further details.
  • A participant seeks clarification on calculating the vector cross product for a beta particle in a perpendicular magnetic field.
  • It is noted that the direction of the force can be determined using the expression (qv)x(B), with the direction depending on the sign of the charge (q).

Areas of Agreement / Disagreement

Participants generally agree on the relevance of the Lorentz force equation, but there is no consensus on the specifics of calculating the vector cross product or the implications for different charged particles.

Contextual Notes

The discussion does not resolve the details of the vector cross product calculation or the implications of the charge sign on the direction of the force.

Just wondering, is there an equation for the force exerted on a charged particle moving perpendicularly through a magnetic field?

Ah I see, but how do I get the vector cross product for something like a beta particle passing though a magnetic field which is perpendicular to it?

The direction is found using (qv)x(B). So depending on the sign of q, your vector will point in one of two possible directions.
 
Ah Excellent. Thanks you two.
