magnetic force 300KG is vertical pull-force which make the magnet pull
way from the thick 30mm steel plate of a tensile tester under ideal
condition. The actual pull force will vary mainly depending on the
following variables:

A: Steel thickness (The thicker the steel is, the stronger the pull force)

Pulling direction (The smaller the angle taking 90° as a standard, the
stronger the pull force), the Pull force in horizontal direction is only
about one third of that in vertical direction)

C: Attracting position (The farther beyond the center of gravity of the attracted object, the lower the pull force)
