Interesting Fishing Magnet Information
The magnets Vertical Pull Strength Rating of 350kg is measured in laboratory conditions using a solid steel plate which is 10mm thick with the magnet placed in the centre of the plate and positioned horizontally on top. An instrument that measures force pulls the magnet steadily upwards at a constant pulling speed of 80mm per minute. The force in kilograms, at the point just prior to the magnet breaking away from the steel plate, is recorded and constitutes the magnets vertical pull strength rating.
