What is a magnet? - Northern Highlands
... The interaction between two magnets really occurs in two steps. First, a magnet creates a magnetic field. Then the magnetic field creates forces on other magnets. In the drawing the field is represented by the arrows. ...

Ampere*turn versus mT and Gauss
... using only one magnet pole will require about twice as much magnetic field compared to activating using both poles. This rule is an order-of-magnitude approximation. A specific case could vary from this by a factor of 2 or more. See Fig.1 for a graph showing specific relationships for specific magne ...

Magnetic Particle Testing
... According to their interaction with a magnetic field, materials can be classified as: Diamagnetic materials which have a weak, negative susceptibility to magnetic fields. Diamagnetic materials are slightly repelled by a magnetic field and the material does not retain the magnetic properties when the ...
