How to use the Magnus Force Calculator

  1. Fill in the values you know. Fields already contain typical example values that you can overwrite.
  2. Pick the unit for each measurement with the selector beside the field; changing a unit converts the number for you.
  3. Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
  4. A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.

If a value is missing or does not make sense, the field shows a short message explaining what to fix.

Formulas used

This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:

density = fluid

vortex_strength = 2 × pi × radius × rotational_speed

rotational_speed = 2 × pi × radius × rate_of_rotation

magnus_force = density × vortex_strength × free_stream_velocity × length

angular_velocity = 2 × pi × rate_of_rotation

About this calculator

The Magnus Force Calculator is a specialized tool designed to determine the lift force acting on a spinning object, such as a ball or a cylinder, due to the Magnus effect. This phenomenon occurs when a rotating body moves through a fluid, causing a pressure differential that results in a secondary force acting perpendicular to the direction of motion. Whether you’re a sports enthusiast, an engineer, or a physics student, understanding this concept is crucial in many applications, from optimizing sports techniques to improving aerodynamic designs.
