This is just a VERY short video showing something very interesting. One of my viewers asked me if a small spherical magnet spins as it travels along the isopotential curve towards a big magnet. So I attached a little tail to the small magnet to show that it does in fact spin as it is travelling. Notice that the small magnet doesn't fly directly to the big magnet, but follows a curved path until it gets a certain distance to the big magnet. Then it flies to the big magnet. The main point though is that the small magnet does in fact spin as it moves towards the big magnet.

![Demystifying the Ferrocell : Part1
In this next series of videos, I will explain to you exactly the steps I took to simulate the ferrocell as I showed in the previous teaser video. NOTE: the volume of this video might be lower than usual since I accidentally recorded with the system microphone and not the better mic that I have and so you may need to turn up your volume for this one.

Here is my Python code for generating the magnetic moments:
import random
from magpylib.source.magnet import Cylinder
magnet_Height= 25
magnet_Diameter= 20
magnet_Strength = 14800
ferrocell_Diameter = 50
ferrocell_Height = 10
ferrocell_Half = 5
thickness = 0.001
s = Cylinder( mag = [0,0,magnet_Strength], dim = [magnet_Diameter,magnet_Height])
f = open(c:/Magnets/MagneticField_300000_2.txt, a)
for x in range(300000):
x = (random.random() *ferrocell_Diameter) -ferrocell_Diameter/2
y = (random.random() *ferrocell_Diameter) -ferrocell_Diameter/2
z =magnet_Height +ferrocell_Half + (random.random() * thickness)
v = s.getB([x,y,z])
f .write(str(x) + + str(y) + + str(z) + + str(v[0]) + + str(v[1]) + + str(v[2]) + n)
