I have read the forum textbook about E/M, the relevant section of ARRL-2014 and have watched 2-3 videos on youtube. It's all clear how things work but I don't get a clue about what each magnetic unit of measurement really means.
In the attached diagram, I know that what I 'm really asking is the force (in kg or Newtons) that the electromagnet pulls the black rectangle, and from what I have understood so far this force is a function of:
1. Current through the coil (I) -Linear
2. Number of coil turns (n) -Linear
3. distance between coil and rectangle - inverse square (double distance = 4 times less force)
4. Properties of the material that the rectangle is made of (retentivity?)
5. Properties of the meterial in the center of the coil (permeability?)
6. Not sure if the diameter of the coil (d) and the surface of the rectangle are parts of the equation
Is there an equation to calculate Force taking account of all these variables and how all these variables relate to Gilbert, Maxwell, Oersted, Gauss . Is there any place to explain more extensively these terms?
