Magnetic poles on a countersunk magnetic disc
|
|
|
 |
|
The magnetic poles of a countersunk magnetic disc can be magnetised in two ways; axially and diametrically. The two varieties of magnetisation allow disc magnets to be used for a greater range of uses.
An axially magnetised disc magnet is magnetised through the length of the magnet, whereas a diametrically magnetised magnet is magnetised through the diameter. The most common form available is axially magnetised. |

On some countersunk magnetic discs the north pole is indicated by a dimple. |

Countersunk hole on a countersunk magnetic disc
|
|
|
 |
|
A countersunk hole has a flat top on one magnetic face which tapers towards the other, in the shape of a cone.
A countersunk hole allows the magnet to be attached to a surface with a countersunk screw. This keeps the surface flat, as the screw, due to the countersunk hole, is allowed to sit level with the countersunk magnetic disc. |

Countersunk magnetic disc keeper
|
|
|
 |
|
The steel keeper on a countersunk magnetic disc must be removed before use to allow the magnet to work to its full potential. The keeper is a soft piece of iron temporarily added between the two countersunk magnetic discs to prevent them from demagnetising. |
