Question

1. To find the value for the permeability of free space, first convert your slope from gauss units to tesla units by using the following conversion (1 gauss = 10?4tesla). .00035 teslas

2. Rearrange the equation to solve for the permeability of free space (?0). Remember that the slope is the ratio of magnetic field to current or ?0=

?0= ______________ T

To find the value for the permeability of free space, first convert your slope from gauss units to tesla units by using the following conversion (1 gauss = 10?4 tesla). .00035 teslas Rearrange the equation to solve for the permeability of free space (?0). Remember that the slope is the ratio of magnetic field to current or ?0 = Compare the percent error between your value and the accepted value of 1.26 x10-6 T · m/A. (Use the accepted value given to three significant figures in your calculation.).

Explanation / Answer

.B = u0NI/2pi R

u0 = B (2 pi R)/NI

u0 = 2* 0.00035*(0.039/2) /100*3.5)

u0 =0.136 *10^-6 Tm/A

c. %error = 0.136-1.26)/1.26 = 89.2 %
