Hi! This be my first post here.
Just a while ago, I stuck my dead-battery-powered Fenix E01 to a stack of neodymium magnets, and noticed that the beam got a lot brighter... not as bright as with a new battery, but still something worth pondering on :thinking:.

After a bit more tinkering with the positioning of the magnets, I found out that it happens when the magnets are put on a certain part of the head.

Anyone have any ideas on what might cause this? Any volunteers want to test current draw and light output with a "magnetized" E01?

Please don't blame me if you fry your light with your homemade soda-can-crushing electromagnet :rolleyes:

The magnet is pulling the remaining electrons out of the battery, thus making the light brighter :D

But seriously, I have no idea :shrug:
 
the light has a boost circuit that uses a coil as a transformer which generates an electric field which can be disrupted or influenced by a magnet. It is not a good idea to have a magnet near the coil when using it in case you cause the circuit to pull more power through than it is designed to handle..... burning it up or cause a more severe overdrive of the LED reducing its life dramatically or frying it.

Pssst... :sssh:
Not electric, magnetic. And it's an inductor, not transformer.



(just being nitpicky... ignore me ;))
 
do you have any pic for the connection for the magnet?
I don't have my camera anymore, so....

The polarity doesn't seem to matter much, but the position of the magnet around the head does. The stronger the magnet, the less accurate you have to be in positioning it...
 
Hi,
This is also my first post. Most boost circuits have an inductor with a iron or ferrite core to increase the inductance by providing a low impedance for the magnetic field. When the magnetic flux in the core reaches a point called saturation an increase in current will not result in an increase in magnetic flux. If an external magnetic field passes through the core it may saturate the core in the case when the external field is in the same direction as the circuit field or increase the required current to saturate the core when the fields are opposite. In either case the operation of the inductor may be effected.
 
This will explain it.

It's a drawn reciprocating dingle arm to reduce sinusoidal
depleneration.
For a number of years now, work has has been proceeding in order to bring
prefection to the crudely conceived idea of a machine that would work to not
only supply inverse reactive current, for use in unilateral phase detectors, but
would also be capable of automatically synchronising cardinal grammeters. Such
a machine is the 'Turboencabulator'. Basically, the only new principle involved
is that instead of the power being generated by the relaxive motion of
conductors and fluxes, it is produced by the modial interactions of magneto-
reluctance and capacitive directance.
The original machine had a base-plate of prefabulated amulite, surrounded by a
malleable logarithmic casing in such a way that the two spurving bearings were
in direct line with the pentametric fan, the latter consisted simply of six
hydrocoptic marzelvanes, so fitted to the ambifacient lunar vaneshaft that side
fumbling was effectively prevented. The main winding was of the normal lotus-
o-delta type placed in panendermic semiboloid solts in the stator, every seventh
conductor being connected by a non-reversible termic pipe to the differential
girdlespring on the 'up' end of the grammeter.
Forty-one manestically placed grouting brushes were arrranged to feed into the
rotor slip stream a mixture of high S-value phenyhydrobenzamine and 5 percent
reminative tetraiodohexamine. Both these liquids have specific pericosities
given by p=2.4 Cn where n is the diathecial evolute of retrograde temperature
phase disposition and C is the Chomondeley's annual grillage coefficient.
Initially, n was measured with the aid of a metapolar pilfrometer, but up to the
present date nothing has been found to equal the transcetental hopper dadoscope.
Electrical engineers will appreciate the difficulty of nubbing together a
regurgitative purwell and a superaminative wennel-sprocket. Indeed, this proved
to be a stumbling block to further development until, in 1943, it was found that
the use of anhydrous nagling pins enabled a kyptonastic boiling shim to be
tankered.
The early attempts to construct a sufficiently robust spiral decommutator failed
largely because of lack of appreciation of the large quasi-pietic stresses in
the gremlin studs; the latter were specially designed to hold the roffit bars to
the spamshaft. When, however, it was discovered that wending could be prevented
by the simple addition of teeth to socket, almost perfect running was secured.
The operating point is maintained as near as possible to the HF rem peak by
constantly fromaging the bituminous spandrels. This is a distinct advance on
the standard nivelsheave in that no drammock oil is required after the phase
detractors have remissed.
Undoubtedly, the turboencabulator has now reached a very high level of technical
development. It has been successfully used for operating nofer trunnions. In
addition, whenever a barescent skor motion is required, it may be employed in
conjunction with a drawn reciprocating dingle arm to reduce sinusoidal
depleneration.

Darn! Why didn't I think of that? It's always the simple stuff staring you right in the face that gets away!
 
I was thinking that the magnet might affect the circuit switching between full on and moon mode. If the magnet is disrupting the light being in moon mode, it might switch to direct drive and drain the battery quicker at a higher brightness. But I'm no expert.
 
Hey, 2manybikes, what brand of hooch are you drinking? Gotta get me some of that. :drunk:

What is scary is if you get a hold of some tech papers on some scientific subject of some cutting edge technology, they can sound just a bad.

The same trick works with CFLs. However, it usually shuts the CFL down. The effect on the inductance seems to stop the oscillator from running. Removing the magnets restores normal operation.
 
Congratulations you have discovered how to tap the zero point energy of the universe...the energy company ninja's will arrive shortly, don't bother running.. :twothumbs
