Magnet Strength Comparison

Magnet Strength - Holding Power

Flexible Magnetic Sheeting is best suited for adhering labels, signs and decorations to metal surfaces.
Flexible Magnets have much less magnetic pull than Rigid Magnets (search for Neodymium & Ceramic magnets).
Flexible Magnets are much less expensive than Rigid Magnets.

Magnetic Strength varies greatly depending on the distance of the magnet to the metal. When possible, place the magnet directly on the metal surface. Affix the item to be held to the face of the magnet rather than under the magnet. For vehicle purposes, use 0.030 magnet - the thicker 0.060 catches more wind and is less effective even though it has higher magnetic strength. The following test results are based on 1 sheet of magnet 2x3.5 inches (business card size) placed on a factory painted steel filing cabinet. Your results my vary.
