Reels with mag brake

[Mikestoys71]

How does a magnet work on an aluminum spool?

[thorhammer]

Coriolis effect.

[redsetta]

It's about conductivity rather than attraction.
These may be of interest...

I thought it was eddy currents?

[MarkT]

It's due to the Lenz law. The spool is affected by the magnetic field even though it isn't itself magnetic.

So it's FM.  F@uckin magic

Exactly

[Cor]

I have been using this for at least 20 years with huge success, but now you guys are confusing me.

So it's FM.  F@uckin magic

seems to be the most correct.

When a conductive but non-magnetic object spins rapidly in a magnetic field a current is produced. But there's no such thing as free electricity (or we'd all be powering our houses with freespool). So this also results in a force opposite the direction of rotation. What you get is a braking effect that is only felt when the spool is spinning fast.

Don't know if this will work?
Edit: this is the link, from a previous discussion here, about Magging reels back in 2017
Hope this helps!
