Answer:
B=0.06345T
Explanation:
The magnetic field at the center of the solenoid can be calculated with the formula:
[tex]B=\frac{\mu_0NI}{L}[/tex]
where [tex]\mu_0=4\pi\times10^{-7}N/A^2[/tex] is the vacuum permeability, and for our values is:
[tex]B=\frac{(4\pi\times10^{-7}N/A^2)(891)(5.95A)}{(0.105m)}=0.06345T[/tex]
