	Theory
		While coilguns don't have any industrial application at present, there have been suggestions that these systems could be used to launch payloads into orbit.
		The second type is the induction coilgun in which the accelerating force is repulsive and comes from the eddy currents induced in the projectile when the coil is 'fired'.
		(2) It is termed a reluctance coilgun because the force acts to move the projectile in the direction of decreasing magnetic reluctance.

	CoilOsapien - Robosapien V2 Coilgun
		A coilgun uses a coil of wire and a pulse of energy to create a short, intense electromagnetic field to fire a ferrite projectile.
		There are many types of coilguns including those that use multiple coils in series and timing circuits to achieve maximum efficiency.
		CoilOsapien uses the simplest of the coilgun designs which is a single stage coil with no timing circuit.

	Orbital Coilgun
		A rocket or a gun carries cargo to an orbital coilgun.
		The orbital energy of the coilgun is replenished by electrodynamic tethers and by launching empty rockets backward.
		The orbital coilgun is prone to buckling unless it is segmented like the electrotube.

	World's Coilgun Arsenal
		Coilgun - A coilgun uses a solenoid to accelerate an object towards the intended target.
		The coilgun is driven by an battery pack with 10-12 'discman-size' LiMH rechargeable batteries.
		Coilgun weight is 1155 g powered by six AA NiCd accu.

	Barry's Coilgun Design Site
		A coilgun is foremost an example of a solenoid.
		A coilgun is also an example of a simple linear motor.
		A coilgun is scalable to very large applications, possibly as large as a mass driver to put payloads into orbit.

	Coilgun
		A conductive projectile is accelerated by a quickly changing magnetic field produced by stationary coils.
		An optional plasma window separates the vacuum inside the coilgun from the atmosphere.
		The demand for electric power is much lower than that of the railgun, especially if the coilgun is long.

	[No title]
		With the energy considerations being what they are, every bit of efficiency in the production of driving flux and volumetric efficiency in a coil driver will be important.
		This set of stuff is just some observations on how one might do a better job on winding a coilgun's coils and arranging those coils for best efficiency.
		One problem has shown up in all the coils I've seen pictures of.
