A: The surface magnetic field strength of magnets of the same shape and size is ranked from high to low, followed by neodymium iron boron > cobalt > aluminum nickel cobalt > ferrite > rubber magnet.
Example: Cylinder D10x5mm
Neodymium Magnet: 4,200 Gauss
Cobalt: 3,300 Gaussian
Ferrite: 1,200 Gaussian
