Static magging a Penn torque and other reels

[REEFMAN]

For Mike... this is how I did my Saltists...

[LGF]

I feel terrible, that I have not finished the tut yet, will do my utmost this morning, BUT this is important:
 
Placement of the mags should be considered with the spool's shaft in mind and not the side wall of the spool, the magnets have absolutely no effect on the spool itself but rather on the shaft. Have taken pics to illustrate.
 
Also the magnets are rather brittle, not an issue as such but because they are so powerfull, they tend to reach some speed in the process of coming together (even when you hold them in two hands) the force is strong enough that if you do not conscientiously (spelling) hold onto them tighter that they will actually rip out of one or both hands and snap together, and this is a problem. Because they are brittle, they tend to either chip or completely crack (one did) so, please keep their strength in mind when you's will work with them.

[BAUMANNATOR]

This is incorrect. The placement has everything to do with the spool, not the shaft. The 'nobby' arrangements on the tournament reels are as distant from the shaft as possible and only affect the spool.

[Hooch]

So, theoretically this will not work on Bakelite spools? Bud, if you follow LGF's advice and forming an eddie on the shaft and not the spool, this can then be done on any reel. His explanation makes most sense. Works on the same principle as a starter motor on a car when forming the eddie on the shaft and not the spool.

Ok just let me correct my own ommission, It does not have an effect on the spools' side wall or spool itself, if the spool is made of aluminium, as aluminium have no magnetic properties, the spools' shaft however is made of steel, be it stainless or other, it does have magnetic properties

[LGF]

lemme see if I can quickly load the pic proving this.
 
These magnets are really strong and the smallest of then 5mmDx1.5mmT will react with each other over a flat distance (on my wooden desk at work) of up to 13cm's.
In the pic, it is right next to an aluminium mold, nothing!, but it is able to get stuck to a screwdriver.

[sparky]

aluminium is not magnetic it's conductive, there has to be motion involved to generate the eddy currents, if that magnet was big enough and you had to drop it onto the chunk of aluminium it would sort of cushion itself against the fall

[LGF]

aluminium is not magnetic it's conductive, there has to be motion involved to generate the eddy currents

Ok, I hear you. Would that then be the same for copper, wrt to it being conductive (not too sure if it behaves the magnetically the same as aluminium)

Some more info regarding eddy currents and the braking effect.
 
 How eddy currents are made  What if the conductor you're moving through the magnetic field isn't a wire that allows the electricity to flow neatly away? You still get electric currents, but instead of flowing off somewhere, they swirl about inside the material. These are what we call eddy currents. They're electric currents generated inside a conductor by a magnetic field that can't flow away so they swirl around instead, dissipating their energy as heat.
One of the interesting things about eddy currents is that they're not completely random: they flow in a particular way to try to stop whatever it is that causes them. This is an example of another bit of electromagnetism called Lenz's law (it follows on from another law called the conservation of energy, and it's built into the four equations summarizing electromagnetism that were set out by James Clerk Maxwell).
Here's an example. Suppose you drop a coin-shaped magnet down the inside of a plastic pipe. It might take a half second to get to the bottom. Now repeat the same experiment with a copper pipe and you'll find your magnet takes much longer (maybe three or four seconds) to make exactly the same journey. Eddy currents are the reason. When the magnet falls through the pipe, you have a magnetic field moving through a stationary conductor (which is exactly the same as a conductor moving through a stationary magnetic field). That creates electric currents in the conductor—eddy currents, in fact. Now we know from the laws of electromagnetism that when a current flows in a conductor, it produces a magnetic field. So the eddy currents generate their own magnetic field. Lenz's law tells us that this magnetic field will try to oppose its cause, which is the falling magnet. So the eddy currents and the second magnetic field produce an upward force on the magnet that tries to stop it from falling. That's why it falls more slowly. In other words, the eddy currents produce a braking effect on the falling magnet.
It's because eddy currents always oppose whatever causes them that we can use them as brakes in vehicles, engines, and other machines.

[MIKE PIKE]

And some more ...
 
 How does an eddy current brake stop something moving?  Suppose we have a railroad train that's actually a huge solid block of copper mounted on wheels. Let's say it's hurtling along at high speed and we want to stop it. We could apply friction brakes to the wheels—or we could stop it with eddy currents. How? What if we put a giant magnet next to the track so the train had to pass nearby. As the copper approached the magnet, eddy currents would be generated (or "induced") inside the copper, which would produce their own magnetic field. Eddy currents in different parts of the copper would try to work in different ways. As the front part of the train approached the magnet, eddy currents in that bit of the copper would try to generate a repulsive magnetic field (to slow down the copper's approach to the magnet). As the front part passed by, slowing down, the currents there would reverse, generating an attractive magnetic field that tried to pull the train back again (again, slowing it down). The copper would heat up as the eddy currents swirled inside it, gaining the kinetic energy lost by the train as it slowed down. It might sound like a strange way to stop a train, but it really does work. You'll find the proof of it in many rollercoaster cars, which use magnetic brakes like this, mounted on the side of the track, to slow them down.

Last one courtsey of Wikipedia. the only difference here is that we are doing is keeping the magnet stationary  and the spool is revolving .

@  BAUMANNATOR humbly beg your pardon  and here and now concede that You ARE  right  and I was WRONG. Please forgive me for not believing you.
 
I did not understand  the processes regarding the movement (of conductive, non-magnetic material), which then generates the "Eddy's" that then causes the secondary magnetic fileds in the conductive material which then acts in an opposing manner to the initial magnetic fields. Now I do (I Hope?), thanx to Chritosch, Sparky and Mike-Pike, thanx Guys and a huge " ful" sorry to BAUMANNATOR again and to all those, Hooch, that I confused with my lack of understanding? Guys?

[sparky]

no worries, we all learn something new every day, takes quite a bit of imagination to actually believe how this principle works

[MIKE PIKE]

Yep took me a while to get my head around this concept as well , invisible things worry me ...

Henk, its do able on the shaft or the spool. With bakelite you can do it on the shaft and on the new modern reels do it from the inside of the housing.

Ok that makes sense too, I just completely missed the whole point of the aluminium spools and the Eddy's generated.

LGF, no need to apologise. I was amped when I first got into trying this on a reel. I see quite a few people are getting excited by the possibilities....that is why I shared my mod ...to get people to think out of the box.

Thanx for being so kind, it defs tells a lot about your character! Now before I get it wrong again, the whole idea concerning the placement of the mags, I would presume would then to focus on the area where the highest speed of the spool wall would reach (as far away from the shaft as possible) and secondly to place them as close to the surface of the spool wall as possible, without actually making contact? Anyhow, that is what I got for the 15 or so odd clips I watched today. Is that correct or am I off the wagon and into the field chasing squirrels again
