I suppose you want to do this on the cheap jerry. Well there are some ways to do this, though they will not be as
powerful as the ones specially made.
The oldest way is to take a bar of soft iron and stroke it in one direction over and over with one of the poles of a
strong magnet. This creates a fairly good magnet. You then bend the iron bar in the required shape. Do NOT use
heat to shape the newly made magnet as the heat will destroy the magnetic field. Any additional shaping can be
done by filing, taking care not to warm up the metal.
The other way is to use a standard magnet and extend the poles with a specially shaped piece of a ferromagnetic
material of some sort. You could even use iron filings held together with some resin or ground up ferrite
reconstituted with some sort of thin glue etc. The magnetic field will extend through the added material giving you
the required field characteristics.
Hope to have been of some help
