Aluminum Spool And Magnetic Brake?


Recommended Posts

I picked up a quantum reel and tore it apart to clean it, noticed the magnet on didn't effect the spool in the slightest of manner... Wouldn't the spool have to be magnetic for the braking system to work?

On reel with mag brakes the magnetic force is applied to either the spool itself or a part attached to the spool as in the inductor referenced. Without knowing the model of the reel no one can help you diagnose why the brakes are not functioning correctly. Chances are the adjustment knob that moves the brakes closer and further away is malfunctioning.

If you move a conductor, in this case the aluminum spool, in a magnetic field, a current is generated which produces a magnetic field opposed the applied magnetic field. Factors affecting the strength of the opposing field, thus the braking force, are strength of the applied magnetic filed, number of force lines interrupted (distance), and speed.

Great explanation of Daiwa Magforce braking. This is why it is one of the most advanced braking systems available and the 3D braking only enhances its ability to be optimized.  With the ability to change the depth the tip of the inductor can reach into the magnetic field, the ability to change the strength of the magnetic field by aligning or misaligning the magnetic poles, and the centrifugal force actuated inductor, you have a lot of ability to finely tune the amount of braking you desire, and the braking system itself has the ability to quickly react to changes such as cross winds  and help prevent over runs.   Of all the braking systems available ,minus the DC systems,  there is nothing that is as advanced as the magforce braking design.

Daiwas are the only non-centrifugal brake reels I'll use, every other one I've tried are A$$.

the reel only says nitrous on it, and even with the magnet and spool do i feel any grap or pull on the two, idk it was for about 75 dollars at dicks. I'm going to dicks in the morning to pick up a new tatula, i just dont see any diiference witht he reel drag set at ten or zero when casting. I guess I got what i paid for.

The Tatula will be a better quality reel and will perform well for you.  If you want to play with the one you have to see the brakes work, if they do in fact work, try this.  Take the line off the spool or tape it down, turn the magnetic settings all the way to zero, and remove all tension on the spool tension cap.  Press the thumb bar down and spin the spool with your thumb, now turn the magnets all they way up and spin the spool again in a similar fashion, you should be able to see a difference in the amount of time the spool free spins.

Daiwas brakes are really neat, but they do use centrifugal forces.  With the exception of the Laguna, Daiwa magforce reels use centrifugal forces to push the inductor closer to the magnet.  A lot of people talk crap about Daiwa because they do not understand the braking system they use.     

 

The current gen BPS Extreme reel uses a Daiwa Laguna style magforce and a 4 pin centrifugal brake.  I think my Extreme is turning me into a Daiwa convert.

I'll try this when I get home. Hopefully it works because the only thing I use this rod for right now really is flipping cover and throwing jigs...

I picked up my tatula and I could see the difference but on the quantum nothing. It's just a cheap combo from dicks for 79.00. I think that's why, I touched the magnets to a piece of metal and it stuck so... Idk lol I'm out of answers. The adjuster goes in an out but there's no magnetic activity between the magnets and the spool.

There are two types of magnetic brake designs. The old standard works with magnets and a (steel flat disk) attached to the aluminum spool. this is a "constant brake", the magnets pull on the disk throughout the entire cast (It's pull is the same at slow or fast speed but speed overcomes the pull). The other method works on the physics principle called the "eddy effect", where a "non ferrous" (aluminum) spool (while spinning) breaks that magnetic field which in turn acts as a brake. The advantage here is that the "eddy effect" is strongest at fast speed. As your lure slows down, the effect becomes less and less. Meaning, you get the brake when you need it (to prevent a birds nest). The cast can go further because breaking is reduced as the lure slows down. You get the opposite reaction on a "constant brake" which works best at slow speed and less at high speed, so you have to tweak in a higher brake setting to avoid a bird nest. Anyhow, that's how I understand it. Something I had to ask about when I purchased a KastKing baitcaster reel.

Cargo shorts on… ready… set… go

 

Perhaps this demo will help. 30seconds in. Movement is relative to the magnet and aluminum. Skip the better performance of the supercooled stuff — that probably aint gonna be on a reel. Physics.

Very interesting video ~ Thanks for sharing it.

Couldn't help but notice that it seemed like for some of the 'experiments',

Sir Isaac Newton wasn't wearing pants.

Perhaps the presence of a metal zipper would interfere with the results.

Lenz effect will make a beer can magnetic - electromagnetic induction - makes you want to drink another beer and think about it... as if you guys need an excuse

Interesting 🤔 I wonder if I can tap into this and run a led light for night fishing or charge a battery.  And it is generating a little heat. 😁 I never knew that my reel was generating electricity, even if it is only within the spool metal.  BTW I have that flashlight.
