In this video, I use MUA to solve a real life problem related to lasers. Of course, MUA is of no value unless you can use it to solve real life problems in a logical and reasonable manner. In other words, you should be able to reason your way through the problem if and when you forget the "shut up and calculate" equations that your teacher taught you.
Just so you know, I sped up my video a little bit to make the video a slightly shorter. This had the added effect of shifting my voice to a higher frequency. I just tried it as an experiment and I liked it. So I kept the sped up version. Hope you don't mind.

![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)
