I want to build a magnetizer for charging / magnetizing small alnico magnets for that I am thinking to discharge a cap into a air core solenoid.
The magnet to be charged would be kept within this solenoid.
The magnet would be of cylindrical geometry and 5mm dia and 10mm length, after searching on the web I have found that alnico needs a field strength of
3000 Oersted or around
I find that
Oersted is related to
Ampere/meter as both of these are units of field intensity but I don't know how to relate oersted to ampere-turns.
To generate this field intensity I would like to know how many turns to wind and how much ampere's to dump into the coil.
Any clues would be of great help.
