# Problem: As the number of loops in a current-carrying wire is increased, thea. more spread out is the magnetic fieldb. weaker the currentc. stronger the enclosed magnetic field.

###### FREE Expert Solution

The magnetic field produced by loops and solenoids:

$\overline{){\mathbf{B}}{\mathbf{=}}\frac{{\mathbf{\mu }}_{\mathbf{0}}\mathbf{I}}{\mathbf{2}\mathbf{R}}{\mathbf{N}}}$, where B is the magnetic field at the center of the loops, R is the radius of the loop, I is current, and N is the number of loops.
