Actually you shouldn't have to mess with reverse polarity or such.

Why not install small electromagnets on the items in question as well so when turned on they are the same pole as your electromag holster.

Since two same pole magnets repel, that should provide some momentum, kicking the item up and out.

THIS could would.


Keep in mind that when dealing with magnetics/electro-magnets, there are 2 forces at work.

The strength of the field in Webbers. (Yea, thats as far as my knowledge goes)
And the Retentivity of the substance. Some things, like rate natural earth magnets that a HUGE Retentivity. Others such as steel, have a low retentivity.

The point? "Positive" and "negative" charge losing meaning real quick... they are either pulled toward the webber field and absobed (their webber field is forced into the same shape, thus they "magnetically" become one.), or they are pushed away. Your "positive charged" item stays that way until you stick it to the magnet. It then becomes "one" with the magnet, its retative "positive" charge is gone.


And keep in mind too, that is all we are talking about here is an object's relative polarity more or less negative then some else... nothing is "positive", it is just "less negative".

[The Wyrm Ouroboros]

Actually, as per, uh, magnetism, there is a 'positive' and a 'negative' - or a north and a south - pole to every electromagnet.  Magnetism will only shoot something away, however, if you've managed to match up identical poles, i.e. 'south to south' or 'north to north'.  Both poles, however, will draw unmagnetized steel, so you can't propel an object via a magnetic grip.

Magnetic acceleration weapons (of which the railgun is only one) exploit various properties of electromagnetism for their item propulsion.  One such is the 'carousel gun', which puts a slug inside what's essentially a miniature particle accelerator - which speeds the thing up by turning magnets on and off in sequence in order to keep pulling the slug forward in a faster and faster loop, until it directs it down the barrel.

Personally I had the thought of having them installed in different parts of the body, thighs and back mostly, have have weapons rigged up so they cling to the points that the magnetic systems are. Could even do a little coding and make it so you can reverse the polarity from attraction to repulsion with a thought and have the system basically launch the weapon right into your waiting hand, making for an even faster quick draw!

They have those for Power Armor in 40k... but remember a whole lot of stuff is made with nonferrous materials. Certain weapons might need a mod to let them do it.

Strickly speaking you are correct Wyrm, every magnet has a "North and South" (positive and negative).

However with an electro magnet, those poles are created with the thousands (some times tens of thousands), wraps of copper around a soft iron core. Which leads to the positive end..... not being where you think it is :p

(Got a cookie for someone with the right answer!)

[Sendaz]

So you mean like inside an electric motor with all the wraps.

Isn't that where the magnetic field 'poles' kind of do a helical movement along/around the coil bundle?

Like imagine the coil bundle was actually a long bolt and the poles were a nut threaded on it.  As it goes along it rotates while it travels down the path.
Course now we have to imagine a bolt that goes in a circle and a nut that can somehow traverse that.

I remember it's some sort of funny movement like that or maybe I am misremembering it.

[The Wyrm Ouroboros]

In an electromagnet, the poles are not (as Reaver seems to be insinuating) 'point-source outwards'; that's the electrical / magnetic charge of a point-source electrical charge.  In an electromagnet, the poles are dependent on the direction of current through the wire, but remain on the open ends of the coil.

And a carousel gun is a ring of ring-shaped electromagnets, which has one of the poles in the center of the ring, and the other (much more diffuse) pole along the outside edge of the ring.  Like I said, it's a mini-particle accelerator, but it uses a much bigger particle.  Which is why it takes a bit to spin the sucker up to speed.

Magnetic monopoles...

Hypothetical, with inconclusive results in all known experiments.  Contribute something real.

Kinda, but not really. In an electric motor those wraps of copper is what makes electricity, or provides the thrust. (Depending on how you hook it up, electric motors either supply electricity, or force.)

There, the principle is Egen =BLV...
Electric generation = strength of the cut field in Webbers, Length of the conductor, and the speed in which they cut the field....


In an electro magnet, you have the coils of wire generating that Webber field, and no conductor cutting the field to invoke a current....

The invoking of webbers in the wire is what makes the negative charged field of the electro magnet.


Now Wyrm is correct that there IS a positive pole to this electro magnet, my question is "where is the positive pole?"

Give you a clue, its not in the "head" of an electro magnet.....

That's actually where I got the idea from. Just have a weapon side mount (or special upgrade for melee weapons, dependent on the weapon) that goes on and serves as the anchor point for the implant to latch on too. With wireless and electronics being what they are, the system on the gun side could interact with they system on the implant side of have some rather interesting effects. May have to explore this more. Thinking of a safety system that ramps up the mag field to hold the weapon in place and prevent it from being readied if the hand print doesn't match.

[I_AM_ZHOUL!!!]

The Wireless Bonus reduces activate/deactivate down to a Free Action. Seems very reasonable to allow it to be used in a Quickdraw Action with the same (or -1) Threshold for any one handed gun/melee weapon.

That depends entirely on how the electromagnet is constructed - because, y'know, some are bar electromagnets, some are ring, etc.  But indulge us and reveal your pop quiz answer.

[Reaver]

On a crane, the "positive" side is located at the inverter, which is (usually) installed in the case base. That is the only place you are going to find a positive field, and thus a positive pole.

Shadowrun has implemented lots of hypothetical science including cold fusion.  Hypothetical doesn't take it off the future tech table.

Which isn't what we're talking about.
