How to Make a Magnet Stronger HowStuffWorks

Magnet stacking One way to make weak magnets stronger is by stacking more of them together There s a big problem with this though Magnets attract each other in opposite directions which will lower their overall strength If you can find a way to hold or clamp them together so they re aligned in the same direction they will in fact produce

Magnets by Pull Strength Aussie Magnets

This is the amount of effort required to remove the magnet from a piece of un coated 3mm mild steel Thicker metals will increase the pull strength whereas thinner metals will decrease the pull strength of the magnet You should consider the material you will be attaching your magnet to when evaluating the required pull strength
