Magnetism |
I want to know how a magnet which is in the shape of a hollow
cylinder, behaves. The height of the cylinder is about 15cm, and the
radius r1 is 2.5cm
and r2 is 10cm.
In order to make an electro-magnet of the same dimentions, where should
the wire-wrapping start?Where should the terminals of the wire connect
(i.e AC current or DC current?)
What should be the nature of the material of the electro-magnet?
And also the wire.(Give examples)
The power with which the magnet attracts or repels depends on the
electricity input, but how do we measure the magnitude of attraction or
repulsion?Do we have any specific scale for that?
Do we have any material which would prevent the magnet from influencing
the surrounding with its magnetic fields?
Right now i have only these questions, Please answer them, as they
might be useful for my project. The project involves practical things,
so please answer in a very practical point of view.(Theoris without
practice does'nt help)
Thank you,
rAgAv
