Physics, Astronomy & Cosmology / How is magnet size and shape calculated to provide a given magnetic field?
« on: 20/09/2017 20:55:04 »
Please experts on the science of magnetism if they can help me.
I need to calculate the dimensions of the magnets in relation to its weight and the magnitude of the magnetic field.
In the image below you note that I want to raise a magnet 'C' for 45 degrees up.
I'm interested in how to find the optimal characteristics of magnets (dimensions, volume, weight, size). The thickness of the magnet must be 30mm.

The process flow in the picture below would be the following:
By bringing the magnets 'A' to the magnet B, the magnetic field the magnet must be rejected 'B' in a circular arc so that the magnet is lifted 'C' for 45 degrees.
All magnets must be of the same dimensions, weight and volume.
How to calculate the strength (grade), the volume and dimensions of the magnet, so that the power of rejection of 'A' and 'B' magnets, he could lift up the 'C' magnet by lever.
My apologies to the bad English. I hope that you will understand my problem.
Thanks in advance for possible help
