Stacking magnets can make them stronger in some cases, but not always. It depends on the type of magnet and how it is stacked.
Two or more magnets stacked together will exhibit nearly the same strength as a single magnet of the combined size. This is because the magnetic field lines of the two magnets combine, resulting in a stronger overall field.
For example, if you stacked two 1/2 inch diameter x 1/4 inch thick disc magnets to make a 1/2 x 1/2 inch thick combined size, the two magnets would have nearly same strength as a single 1/2 x 1/2 inch magnet.
Does that mean the strength is doubled?
We are often asked if stacking two magnets together will double the pull force. The answer to that is not always. In the example below, you can see how the pull force increases and eventually begins to level off as you continue to double the thickness.
Good customer service, great price & quick to ship
I was hoping to find a strong, low profile magnet to use on my project - which is a restoration of a WWII Army Footlocker. I wanted to attach some old photos and postcards to the underside of the lid, but without using any permanent adhesives which may have affected my paint job. These worked perfectly!
Just what I needed and at the right price.....
Will purchase more when needed.
Have used before & reordered magnets for customized windows alarm contacts. Work fantastic & slim profile allowing no issues opening & closing windows.
me use these to stop 1/24 scale drag racing slot cars !!

Magnetic knife board, that worked perfectly.
More than strong enough for my shop project. Very good value for the money.
Stampin up card projects
I design and make refrigerator magnets for extra money. The magnets work great and provide an inexpensive source.
These magnets work great for my project. Will use this company again. Communication is top notch as well as product and speed of delivery.
