An Electron Has Velocity of 4×10⁶ m/s and Moves in a Circular Orbit in a Magnetic Field of Flux Density 0.6 T. What will be the radius of the orbit?
electron moves in circular orbit in a magnetic field is a classic physics numerical often asked in Class 12, NEB, and CTEVT exams. This problem involves the motion of a charged particle in a magnetic field.
Given
Velocity of electron, v = 4 × 10⁶ m/s
Magnetic flux density, B = 0.6 T
Charge of electron, e = 1.6 × 10⁻¹⁹ C
Mass of electron, m = 9.11 × 10⁻³¹ kg
Concept
When a charged particle such as an electron moves perpendicular to a uniform magnetic field, it experiences a magnetic force that acts as a centripetal force, causing it to move in a circular orbit. The radius of this motion is given by:
r = mv / (eB)
Always use the correct units and convert them where necessary before substituting values in formulas.
