PHYS 1B Lecture Notes - Lecture 16: Right-Hand Rule
Document Summary
Magnetic force law: experiments show: magnetic fields (produced by magnets/electric currents) exert magnetic force on a moving charged particle given by: fb = qv x b. Q is the charge of the particle. *note: one tesla is pretty large magnetic field that requires large magnets to produce, but it is similar to the field used in mri machines. Fb is in the direction of your thumb. Clicker question: suppose v for a positive charge is in the positive x direction and b is in the positive y direction. What is the direction of the force: d) in the positive z direction. Clicker question: suppose v for a positive charge is in the positive z direction and b is in the positive y direction. Clicker question: suppose v for a positive charge is in the negative y direction and b is in the positive z direction. What direction is the force in: b) the negative x direction.
