Examples of helical in the following topics:

  • Helical Motion

    • Helical motion results when the velocity vector is not perpendicular to the magnetic field vector.
    • This produces helical motion (i.e., spiral motion) rather than a circular motion.
    • Describe conditions that lead to the helical motion of a charged particle in the magnetic field
  • Direction of the Magnetic Force: The Right Hand Rule

    • Because the force is always perpendicular to the velocity vector, a pure magnetic field will not accelerate a charged particle in a single direction, however will produce circular or helical motion (a concept explored in more detail in future sections).
  • LCDs

    • The molecules arrange themselves in a helical structure (twisted structure).
  • Springs

    • Plot of applied force F vs. elongation X for a helical spring according to Hooke's law (solid line) and what the actual plot might look like (dashed line).
  • Electric vs. Magnetic Forces

    • The angle dependence of the magnetic field also causes charged particles to move perpendicular to the magnetic field lines in a circular or helical fashion, while a particle in an electric field will move in a straight line along an electric field line.
