Question

Uncertainty in magnetic field of permanent magnet

Answer 1

We must settle for some uncertainty due to the non-ideal shape of the multilayer ... B-field at the axis of a cylindrical permanent magnet.

Answer 2

Answer:

When the magnetic field strength is measured by Guassmeter, the calibration uncertainty is 0.12% (k=2). When the magnetic field strength is measured by Fluxmeter and search coil, the calibration uncertainty is 0.30% (k=2).
