SUMMARY

The discussion centers on finding the direction of force on a charged particle in a magnetic field without relying on the right-hand rule. Participants suggest using the mathematical expression for the Lorentz force, specifically the equation F = q(v × B), where q is the charge, v is the velocity vector, and B is the magnetic field vector. This approach allows for a more analytical understanding of the force's direction by calculating the cross product of the velocity and magnetic field vectors.

PREREQUISITES
  • Understanding of vector mathematics, particularly cross products
  • Familiarity with the Lorentz force equation
  • Basic knowledge of charged particles and magnetic fields
  • Linear algebra concepts, especially vector operations
NEXT STEPS
  • Study the mathematical derivation of the Lorentz force equation
  • Learn about vector cross products in detail
  • Explore applications of the Lorentz force in electromagnetic theory
  • Investigate alternative methods for visualizing magnetic forces on charged particles
USEFUL FOR

Physics students, educators, and anyone interested in electromagnetism and the behavior of charged particles in magnetic fields.

Hi guys
I'm not sure if this is the right area - this is my first post - but it seems like it fits so

My question is, is there a way to get the direction of force on a charged particle from a magnetic field without using the right hand rule? What I'm looking for would be a way to just think about it, rather than look at my hands, or imagine my hands.

Thanks for any answers!

You could calculate ##q\vec v\times \vec B## [and, if needed, get the components]

derp...for someone currently finishing up a linear algebra course.. I should have gotten that xP but thanks a ton!
