Marking a lesson complete represents finishing your study of the topic; it does not denote tested mastery.

Learning Objectives

Manipulate particle charge, speed, mass, and B-field to observe real-time cyclotron orbits and verify r = mv/(qB).
Observe velocity filtering in crossed E and B fields, verifying condition v = E/B for straight passage.
Simulate needle deflection in a moving-coil galvanometer and calculate necessary shunt/multiplier values for real-world current and voltage ranges.

Interactive Magnetic Field & Galvanometer Laboratory

Simulate charged particle motion in magnetic fields, cyclotron orbits, velocity filtering, and moving-coil galvanometer meter conversions.

Particle & Field Controls

Particle Species:

Magnetic Flux Density (B):0.50 T

Particle Speed (v):10^6.0 m/s (1.0e+6 m/s)

Velocity Selector Crossed E-Field:

Cyclotron Orbit Telemetry

Trajectory Radius (r):2.09 cm

Orbital Period (T):131.19 ns

Cyclotron Frequency (f):7.62 MHz

Magnetic Force (F_B = qvB):8.01e-14 N

Key Principle: In a perpendicular field, magnetic force provides centripetal acceleration ($qvB = mv^2/r$). The period $T = 2\pi m / (qB)$ is completely independent of particle speed, allowing resonant cyclotron RF acceleration!
