Nickel Plated 1/2″ Magnet Sphere/C-sunk Ring Set

Nickel Plated Sphere/C-sunk Ring Set

These magnetic sphere and countersunk rings can be used for a wide range of applications. Especially useful in making art dolls, OOAK sculptures, and purses.

Each set contains (1) sphere and (1) countersunk ring

These sphere-shaped magnets are 1/2″ in diameter. They are quite a bit stronger than our 3/8″ spheres and can pinch.

Countersunk Ring:
Dimensions: 1/2″ od x 1/8″ thick with countersunk hole
Tolerances: ±0.004″ x ±0.004″
Material: NdFeB, Grade N42
Plating/Coating: Ni-Cu-Ni (Nickel)
Magnetization Direction: Axial (Poles on Flat Ends)
Weight: 0.0985 oz. (2.79 g)
Pull Force, Case 1: 5.43 lbs
Pull Force, Case 2: 12.55 lbs
Max Operating Temp: 176ºF (80ºC)
Brmax: 13,200 Gauss
BHmax: 42 MGOe
Strong countersunk ring magnets. The north pole is on the side of the magnet with the large hole.
