How Do Magnets Hold?
All magnets have the strongest attraction to other magnets and
metals with high iron content. The thickness of the metal also
contributes to the attraction. If the ferrous metal is too thin, it
cannot hold all the magnetic flux coming from the magnet. All
magnets reach out with magnetic power and hold onto other
magnets and the iron in ferrous metals. If there is more of that
material for the magnetic field to grab, it will hold better.
The Best Hold
•
Magnets exhibit the strongest hold in a direct pull against the load.
N S
•
Magnets are much weaker when the load is sliding across the
magnetic field.
•
To achieve the best hold, the magnet's surface needs to make full
contact with the surface of the ferrous metal.
!
•
If the metal is bumpy or textured, the magnet surface can't

fully connect.
•
Similarly, paint, coatings, and other things in between the two
S
surfaces also reduce the hold.
Pull tests are widely used across the magnetic
industry. Pounds pull ratings are common for
magnetic assemblies, providing users with
accurate insights into each product's capabilities.

How Is Magnetic Pull Strength Determined?
Magnets and magnetic assemblies are measured by a vertical pull test.
Each magnet's entire magnetic surface is tested against a half-inch
thick, ground steel plate. Beginning with a clean magnetic surface and
a clean steel surface, the magnetic assembly is attached to the steel
plate. A hook with the measuring device is attached to the magnet
and it slowly pulls the magnet upward until enough force to break the
magnet away from the plate is created. The measuring device records
the pounds pull. Repeated measurements establish an accurate
reading and pounds pull rating for each magnetic assembly.
Using Your Handle Magnet
Keep these principles in mind, and you will get
the best performance with your handle magnet.
•
Pull directly against the load.
•
Using the magnet in a shearing motion will
decrease the power.
•
The magnet will hold less weight if the metal
lifted is thin and/or has a low iron content.
