## Example 13.1 Page no 252¶

In [8]:
#Given
d=0.1                                 #m
v=10.0**3                               #m/s
a=50                                  #gradient of a magnet field Wb/m**2/m
b=9.274*10**-27                       #J/Wb/m**2
h=1.6605*10**-27

#Calculation
M=107.868*h
z=(b/M)*a*(d**2/v**2)

#Result
print"seperation between the two component ",round(z*10**8,1),"mm"

seperation between the two component  2.6 mm
