 == Force Distribution ==
+Using model #3 described above, the force distribuion from the solenoid is non-linear and very complicated. However, understanding this force distribution is very important in order to determine the characteristics needed for most efficiency. As it can be seen in the picture *, the magnetic field is distributed along the field lines; the density of the magnetic field is proportional to the force applied to a charge in that field.

		+	January 25th, 2015 members of the Mechanical and Elecetrical team sat down in a classroom to talk about the solenoid development.
		+
		+	=== <span class="mw-headline" id="Mechanical_constraints">Mechanical constraints</span> ===
		+
		+	In the beginning of the conversation, some mechanical constraints were applied, such as:
		+
		+	*A, Crossectional area of the armature. This area is set a bit smaller than the crossectional are of the solenoid, leaving as small of a gap between the walls and the armature.
		+	*Solenoid dimensions were set earlier.

		+
		+	=== <span class="mw-headline" id="Model_.231">Model #1</span> ===
		+
		+	Model #1 is the first model considered to describe and analyze the solenoid behavoiur. The main problem of this model was that the armature was viewed only at the instant, when it is completely encompassed in the solenoid. This is a big flaw due to the fact that this model greately limits the travel distance of the armature.
		+
		+	=== <span class="mw-headline" id="Model_.232">Model #2</span> ===
		+
		+	The main deviation from model #1 is that the armarture starts only partially inside of the solenoid (the initial guess was halfway through). A big assumption made in this model is that the magnetic field outside of the solenoid is negligeble in comparison to the magnetic field inside of the solenoid (in order words, the magnetic fields exists onlt insde of the solenoid). An important face noticed by from this model is that once a long (longer than the solenoid) armature fills the solenoid, it would stop moving.

		+	=== <span class="mw-headline" id="Model_.233">Model #3</span> ===
		+
		+	Model #3 is the most realistic model among the ones presented.
