Magnetic Field from a Velocity-Selected Particle
A charged particle passes undeflected through a velocity selector with perpendicular electric and magnetic fields of E = 3.0×10^4 N/C and B = 0.25 T. If the particle continues to move at this constant velocity, what is the magnitude of the magnetic field it produces at a distance of 2.0 cm from its path?
A
1.2×10^-5 T
B
Depends on the particle’s charge
C
3.0×10^4 T
D
Zero
