<p>The question is, was a lipstick tube magnet oriented through the width or the length? I always assumed it was through the width. Whereas the hard drive magnet appears to be oriented through the length, like a science bar magnet. </p>
<p>You may be able to take your pickup as is, and turn it on end and have it work. So it would be like one giant polepiece from a Strat pickup. </p>
<p>On the other hand, it could be that those "rules" about magnet orientation are for weaker alnico and ceramic magnets and it wouldn't matter which way you oriented a hard drive magnet. I don't have any here to play with, so I can't say for sure. <br/><br/>In general, I suggest getting the pickup working without the cover first, then add the cover and see what happens. You can quickly test the pickup by holding it closely over the strings and plucking the strings. </p> I've been trying to strengthe…tag:www.cigarboxnation.com,2017-04-24:2592684:Comment:28536902017-04-24T20:20:22.523ZPaul Craighttps://www.cigarboxnation.com/profile/PaulCraig

<p>Maybe that would work, but it's a lot of trouble using multiple magnets stacked and better off using one magnet that's strong enough. you can always use a strong magnet to strengthen a weaker one, but that takes careful alignment of poles and time.</p>

<p>stacking magnets pole to pole does make a bigger magnet, but these are bar magnets with the poles at the ends stacked side to side. to make it a bigger magnet they need to be end-to-end like linked sausages. stack them side they cancel because they have both a N and a S pole sticking out the same end of the coil.</p>

<p>Stacking magnets shouldn't be a problem. Each magnet has different pole on each side, so stacking a south pole(south on top north on bottom) on top of another south pole would be north on bottom of first attracting to south on top of the other that has north on it's bottom. So result would be S-N-S-N. Effectively becoming one magnet that's the same as a single magnet with South on top and North on bottom.</p>

<p>30 gague wire has 1 ohm per foot, 600 winds is probably in the neighborhood of 100 feet, so your multimeter should register about 100 ohms between your hot and earth lead out wires.</p>
<p>I think your problem is <em>" I left one magnet attached to it, removed the plate from the other magnet and just snapped it ontop of the other"…</em></p>

<p>the poles on those magnets are at the ends. Letting them snap together themselves means you have the N of one and the S of the other against each other. the fields are going just between the magnets and not out to your strings.</p>
<p>remove the second magnet, one of these should be enough. </p>
<p>multi-magnet pickups have to have all the N poles pointing the same direction so as to not cancel each other out, which can be hard to force them to do since they tend to repell each other that way.</p> The magnet needs to be in con…tag:www.cigarboxnation.com,2017-04-21:2592684:Comment:28512332017-04-21T03:13:27.433ZJerryrig240https://www.cigarboxnation.com/profile/Sam
<p>The magnet needs to be in contact with the strings on this one. The magnets need to be bare. So the wire needs to be around the magnet. Like a typical pickup. And I am not sure what wire you are using there, but it needs to be coating. Just old copper wire will not work. Hope this helps. One of the best and easiest pickups you can build with is a sewing bobbin pickup. Wind up a bobbin with wire and use a bolt through it and add a magnet to the bottom. Perfect for one string builds.</p>
