Questions & Answers

Q: How does the direction of an electron's velocity change in a uniform magnetic field?

In a uniform magnetic field, the electron's velocity remains constant in magnitude but changes in direction due to the magnetic force acting on it, causing it to trace circular paths.

Q: What factors influence the deflection of electrons in a magnetic field?

The deflection of electrons is influenced by the magnetic field intensity, electron velocity, distance from the magnetic field to the screen, electron charge, and electron mass.

Q: What formula describes the deflection of electrons in a magnetic field?

The formula for electron deflection (Y) is derived as Y = B * L * e * D / (2 * M * sqrt(2 * e * Va / M)), showcasing the relationship between magnetic field strength, distance, charge, mass, and acceleration voltage.

Q: How is the deflection sensitivity and factor calculated for electron deflection?

The deflection sensitivity (s) is determined as Y / B, and the deflection factor (1/s) is calculated as 1 / (L * D * sqrt(2 * M * Va / e)), providing insights into the efficiency of electron deflection mechanisms.
