This calculator uses the formula of Biot and Savart to compute the magnetic field at the midpoint along the central axis of a slinky. The calculation assumes:
To be accurate, the calculation may take some time. Be patient!
- The coil turns are evenly spaced
- The coil is straight
- No stray magnetic fields from the surroundings (currents, earth's field or magnetic materials nearby)
- The magnetic field sensor is lined up with the coil central axis
