You can use this simulation to examine the magnetic field created by the current in a wire loop. the loop is in the x-z plane, centered on the origin, with a radius of 60 cm initially. the displayed field is in the x-y plane.

(a) given the limits set by the sliders in the simulation, and the two coils you have to choose from, what is the magnitude of the maximum magnetic field that can be obtained at the exact center of the loop? express your answer to three significant figures.

(b) as you move away from the center of the loop along the y-axis, what happens to the magnetic field? (choose only one)

1.both the magnitude and direction of the magnetic field remain the same.
2.the magnitude of the magnetic field stays the same, but its direction changes.
3.the magnitude of the magnetic field increases, but its direction stays the same.
4.the magnitude of the magnetic field increases, and the direction of the field changes.
5.the magnitude of the magnetic field decreases, but its direction stays the same.
6.the magnitude of the magnetic field decreases, and the direction of the field changes.
7.the magnitude of the magnetic field increases until you move some distance from the center and then decreases as you move further away, but the direction of the field stays the same.
8.the magnitude of the magnetic field increases until you reach a certain distance from the center and then decreases as you move further away. in addition, the direction of the field reverses at this certain distance.
9.the answer depends on whether you move away along the y-axis toward positive y values or toward negative y values.
