We Need A Separate Forum for Fuses

Isn't a directional fuse commonly referred to as a diode? ;-)

Uh, no. 😬 A diode allows much more ease of current flow in one direction than the other. 

Addendum: There’s no such thing as a “directional fuse.” They’re all directional. There aren’t any non-directional fuses. Even Littelfuse and Bussman fuses are directional.

Geoff.and perhaps Al... I wonder if part of the directionality of fuses is caused by subtle magnetic fields around each particular application?
Folks talk about the resistance, impedance and inductance of wire.

But one factor not mentioned is the always present magnetic fields.
So I wonder if anyone has done some research on them. There are a few IC which play with magnets, but I would think a lot more could be done.
Also trying to degauss Fuse clips?
Anyway, this thought has been in my mind since my new 20.7 Magnepan Tweeter problem happened.
(in which one channel tweeter wiring was reversed, causing that tweeter to barely make any sound. Until the physical tweeter was inverted. Then it played, However Magnepan is going to replace the speakers The odd thing is the directionality. Why, And I can only account for it by saying the long magnetic field of the tweeter somehow has a polarity,even with AC music waveform. And no it is not the interaction with the midrange, which had the midrange fuse pulled anyway.) I also wonder if the near silent tweeter was getting hotter, The music energy had to be dissipated somehow, but I do not have a digital thermometer.
Also two separate tweeter elements were tried, both behave the same way when sonnected wrong. (the magnepan tweeter is a long strip full of magnets, one terminal at each end, connecting the mylar and foil tweeter ribbon which is surrounded by the magnetic field.)
So I suddenly have been thinking what else could be affected by magnetic fields in my stereo?

Also I have to say a fellow emailed me about my tweeter, and it got me interested. so any credit has to go to some other person who thought it was more than a simple thing.
Anyway, your thoughts?

(I was too late to be able to add to my prior post so...)
An additional though about the subtle ways magnetism affects audiophile sound is the de-magnification of LPs and CDs. Folks find improvements in the sound from this process. So there seem to be plenty of room for experimentation in the area of magnetic fields and audio affects.
I still own a pencil Tape head demagnitizer, and plan on buying some horseshoe magnets to magnetize the fuse holders, then demagnetize and switch the field to see if I an notice any effects on the sound for my fuses in the speakers. (though I am going to wait since the speakers are still going to need breaking it.
(so anyone wanting to do some experiments I have no problem you beating me to any discoveries!)
