GME, where you can find awesome quality, but also great service!









  • Magnet with bolt, 10-24 x 1" length securely-mounted, includes 3 nuts

  • Magnet holds 35 pounds on contact with 1/4" thick, flat, smooth
    ferrous plate in a vertical test, 50% less on vertical surface holding
    against sliding force and less on steel with paint

  • Round base magnet fastener made of chrome plated steel cup containing
    Ceramic, Ferrite magnet with 10-24 x 1" length bolt attached

  • Holding force is concentrated on rim of steel cup and will not hold through a layer of material

  • For indoors and outdoors applications at temperatures between -10 degrees and 200 degrees Fahrenheit

These are powerful neodymium magnets housed inside of a stainless steel cup. 
The cup protects the magnet and also increases the magnets power by redirecting one polarity towards the other side. 
Attached to the cup there is a threaded stud that will work perfectly with a standard nut or threaded hole.


Ceiling magnet include countersunk holes
or threaded features that allow for mounting with standard hardware
(nuts and bolts), as well as various hooks.


Ceiling magnet are intended to attract to a steel (or other ferromagnetic) surface.
Awesome advantages:
More Magnetic Strength: 3-5 times of common neodymium magnet. 
With the steel cup of a mounting magnet,
the steel structure redirects the magnetic field from the back-side of
the magnet, turning it into more useful holding strength. 

The Magnetic force is made stronger because the south pole is redirected to face north.

Durability: Our Mounting Magnets are constructed so that the surface of the magnet is set very slightly below the surface of the steel cup. 
When it hits a steel surface, the steel cup takes the brunt of most impacts.

We would love to see how you have used our magnets




Simply send us a photo of your magnets in use and if we use it on our website we will return you $10 next order (Amount more than $1000).



  Be careful – they’re super strong unexpected!

As always, you can't be more careful when handling strong neodymium magnets.  Handle
these cup magnet with care, especially the larger ones. 




You don’t want to
pinch your finger between magnets that can exert hundreds of pounds of
force!

Speaker Magnets




Every audio speaker has a magnet in it. From subwoofers to iPod
headphones, magnets provide the motive force that makes speakers move.





Although
neodymium magnets were expensive, they allowed loudspeaker motors to be
as little as half the weight of comparable ceramic magnet motors.





Prices of neodymium started coming down and interest in lighter weight speakers grew, as did neodymium speaker options.

neodymium (rare earth) magnets are widely used for motors, one of them is voice coil motors, especially in disk voice coil motors.




Voice Coil Motors (VCM), also called Voice Coil Actuators (VCA), are a
very mature design that utilizes a magnet and yoke in conjunction with a
coil. 





The coil and magnet area concentric about a common axis and
there exists an engineered magnetic return path.






The coil is typically connected to a mechanism which translates the
coil’s linear motion into a beneficial action. 





For example, a
conventional loud-speaker uses a voice coil motor to drive a cone which
converts the coil’s oscillating motion into sound energy.

Key Benefits of a VCM – Voice Coil Actuator:




  • No commutation required

  • Low to no hysteresis

  • Zero cogging

  • Fewer mechanical components compared to “screw-type” actuators

  • Linear control characteristics

  • High power to mass ratio

  • High power to volume ratio

  • Infinite position (Limited only by the encoder device.)

  • High acceleration
