UFox, Moodz is right with his statement about you amateur guys.

But hey, "If you don't know the answer, I'm not going to tell you!" ( )
*LOL*

You are no better than Moodz, ^sif. You are another bloke who has waffled on for years about the world beater you are going to produce (evidently only in your mind) while going absolutely nowhere that hasn't been visited years ago.

Why is Moodz coil an outperformer?
Forum-trolls didn't answer the question.
^sif

Gee ^sif, I would have thought the question would be "Is the Moodz coil an outperformer?" So far, as can be seen again in Moodz's last post on AEGPoof, the only thing that seems to be performing is Moodz's mouth.




Don't you reckon it's a pity he is so full of hot air and has never actually produced anything of consequence?

[Mellow Yellow]

Jeez Asif, you frightened all the Aussie members, they thought you said you were escaping to Australia!

[Aziz]

since austria is part of the euro arrest warrant scheme thats no good switzerland is a safer bet.

No worries. I'm back in the darkness of the night! *LOL*
The weather was really fine there.

Oh! oh!, no answers to my question. Forum-trolls must be lazy or tired. *LOL*

There you have it: too late!!!
I am escaping to Austria now....

[Aziz]

Hurry up man before the capitalist and fashist government Gestapo knocks my door to arrest me or I have to leave the evil country. You know, I'm on the run! I'll escape to Austria soon. And the weather is just fine to cross the border.
Quick!!!! *LOL*

Actually if you knew your subject Peter ( AKA P99 ) ....
Basket weave and litz resolve the issues below ...
Skin effect: The resistance of a wire to high frequency current is higher ....
Proximity effect: Another similar effect that also increases the resistance of the wire at high frequencies
Parasitic capacitance: At a high enough frequency this capacitance can.......

So tell me moodz, do you really believe you are onto anything that others have not fully researched?? You are talking issues that others were aware of more years ago than I care to remember.

[moodz]

Thanks 6666 ... I will be posting more.

[moodz]

Very nice cool coil there Moodz, I especially like the sleek look, but more importantly, no shield to get in the way of all those shy "holey minelab" evading nuggets.

Thanks Kev .. The shield is easily added but will use without to start with.

[6666]

Thanks for the pictures of your coil Moodz

You certainly are a clown Doug. If basket wound coils are that good then every detector manufacturer who wants an edge would be using them. So tell me Doug, are you that stupid that you don't believe that others have made spider or basket wound coils and done extensive measurement?

Actually if you knew your subject Peter ( AKA P99 ) .... there has been alot of research into basket weave coils and litz wire. The main reason you dont see them in commercial coils is manufacturing difficulty coupled with mechanical stability and bulk of the windings. However the use of basket weave in a resin matrix overcomes these difficulties and the basket weave actually reinforces the resin addition to the other benefits. The resin also prevents the windings moving relative to each other which causes instability when the coil is knocked.

Basket weave and litz resolve the issues below ...

• Skin effect: The resistance of a wire to high frequency current is higher than its resistance to direct current because of skin effect. Radio frequency alternating current does not penetrate far into the body of a conductor but travels along its surface. Therefore, in a solid wire, most of the cross sectional area of the wire is not used to conduct the current, which is in a narrow annulus on the surface. This effect increases the resistance of the wire in the coil, which may already have a relatively high resistance due to its length and small diameter.
• Proximity effect: Another similar effect that also increases the resistance of the wire at high frequencies is proximity effect, which occurs in parallel wires that lie close to each other. The individual magnetic field of adjacent turns induces eddy currents in the wire of the coil, which causes the current in the conductor to be concentrated in a thin strip on the side near the adjacent wire. Like skin effect, this reduces the effective cross-sectional area of the wire conducting current, increasing its resistance.
• Parasitic capacitance: The capacitance between individual wire turns of the coil, called parasitic capacitance, does not cause energy losses but can change the behavior of the coil. Each turn of the coil is at a slightly different potential, so the electric field between neighboring turns stores charge on the wire, so the coil acts as if it has a capacitor in parallel with it. At a high enough frequency this capacitance can resonate with the inductance of the coil forming a tuned circuit, causing the coil to become self-resonant.

Let Doug talk Moodz into building a bunch of these coils. Maybe then Moodz will figure out the truth about Doug and run as far away as he can.
