Answer:
[tex]B= 0.0462T[/tex]
Explanation:
Given that;
the diameter = 12.9 cm long
radius = [tex]\frac{d}{2}[/tex] =[tex]\frac{12.9}{2}[/tex]
= 6.45 cm
= 0.0645 m
The expression for the strength of the magnetic field at the center of this solenoid can be given as:
[tex]B = \frac{U_oNI}{2R}[/tex]
[tex]B = \frac{1.26*10^{-6}*789*5.99}{2*0.0645}[/tex]
[tex]B= 0.046162[/tex]
[tex]B= 0.0462T[/tex]
