For rectangle/bar magnets... All our rectangular magnets are magnetized through the thickness.. The poles are always on the surfaces of the 1st two numbers of the measurements.
On round magnets... The poles are always axially magnetized through the thickness...This means the poles are on the flat surfaces unless stated that they are diametrically magnetized which means the poles will be on the curved sides.
Support all magnet plating , like Ni, Zn, Epoxy , Gold, Silver etc.
Pull Force is the amount of force required to separate 2 of the same size magnets from each other.
Actual pull force of cylinder/disc magnets may vary depending on different applications due to the small contact surface, please test them before usage
Rule of thumb is that the magnet will hold approx. 1/3 the weight of the stated pull force. So...If pull force stated is 90 lbs...the magnet will hold approx. 30 lbs in weight hanging from it.
Also..If you are trying to stick the magnet to stainless steel...the better the quality of the stainless steel...the less the magnet will stick.
