Lipstick Pickups

[jolasa]

Regarding lipstick pickups, like invented by DaneElectric back in the 50's.

I am designing a small lipstick pickup.

As we all know, the lipstick pickup consists of:
1. one long alnico magnet, the width of the string
2. wire windings are around the magnet, from one end to the other
3. the wound magnet is enclosed in a chromed metal tube, originally surplus actual Revlon lipstick tubes

Questions:
is the magnet axially magnetized (N at one end, S at other end of the long axis)
or
is the magnet diametrically magnetized (across the diameter or perpendicular to the axis)

I believe the N/S axis is on the top/bottom of the pickup like other single coils. Lipstick tubes are weak because the number of coil turns is constricted by the cover. If they used a neodymium magnet they could cut the size of the magnet down and put more turns on the coil.

Imagine the magnet is a pencil on a table in front of you, the point of the pencil is to the left, the eraser end of pencil is to the right.

So the entire top of the pencil is N, the bottom is S (as opposed to the point of the pencil being N, and the eraser end of the pencil is S)?

The bottom is South and the top is North.

The bottom is South and the top is North.

Aha!

So the magnet is diametrically magnetized (as opposed to axially magnetized).

Winding options, which is best?

long N-S magnet, axially magnetized, wind around top to bottom and left to right

same long magnet, N all along top, S all along bottom, wind left to right [ this is way lipsticks are usually done? ]

Make sense?

Whoa...

The collector in me now wants to find old surplus Revlon lipstick tubes.

Thank you for the explanation of Axially versus Diametrically.

I have a set of lipsticks in one of my Strats and I love them.
