Electric Magnetizer

Does this thing look suitable for charging ALNICO bar and rod magnets?

Looks like you'd have to do one pole at a time.

Doing one pole at a time is not physically possible. Such a thing would be a magnetic monopole which is not known to exist.

To use it, you would complete the magnetic circuit using the bars of iron provided. Looking at the ad, the crucial information, the magnetic field strength, is missing completely from the specification.

There was a great thread here about magetizers here a while back. See if you can find it.

I just emailed them asking what the magnetic field strength is.

Specs...

Here they are, thanks Nick.

Did he mean one pole piece at a time?

They don't give any info on how it works.

[EDIT] OK, from reading the PDF, you would need to stick a magnet in each "well" or hole on the top, and bridge them with the keeper bars. That's assuming the bar magnets have the poles at the ends, and not on the sides, as the magnets we use do.

So this is totally unsuitable for pickup magnets without making major modifications.

Here's that thread I mentioned http://music-electronics-forum.com/t32227/.

A great read and full of practical advice.

A couple Months ago somebody published here a very good pickup magnetizer , with adjustable jaws, properly sized so it would perfectly magnetize a pickup.

EDIT: here it is:

Thanks for the Everyone.
