Making a rather unusual magnet

[rehandalal]

Hi,

I am making myself a humbucking pickup for my guitar and I need a bar magnet with poles running from one long side to the other (refer to http://www.rehandalal.com/magnet.gif" )... It needs to be a relatively strong magnet. So if anyone could offer any suggestions as to what material I should be magnetizing and how to go about magnetizing it would be much appreciated.

Thanks!

I don't know how strong the magnet should be, maybe you could provide a favorable gauss range for us.

The Earth's magnetic field is about 0.6 gauss, and a refrigerator magnet's, between 10 and 100 gauss. If you want it (≥refrigerator magnet) you'll need to buy one.

Hello Rehan,

It's great to hear that you are experimenting with making your own humbucking pickup for your guitar! In terms of creating a strong bar magnet with poles running from one long side to the other, I would recommend using a rare earth magnet such as neodymium or samarium cobalt. These materials have high magnetic strength and can be easily magnetized to create a strong and consistent magnetic field.

To magnetize the material, you can use a process called "magnetic alignment" where the material is exposed to a strong magnetic field and then cooled in that field. This will align the magnetic domains within the material and create a strong and consistent magnetic field.

Alternatively, you can also use a process called "magnetic pulsing" where the material is exposed to a series of strong magnetic pulses, which will also align the magnetic domains and create a strong magnet. This method is often used for creating custom magnets for specific applications.

I hope this helps and good luck with your project! Let us know how it turns out.
