A). No. The direction of the field depends only on the direction of the current, not on its magnitude.

B). No. The magnetic force was there as soon as there was any current. It didn't begin when the current increased.

C). Yes. The magnetic field is increased. More current causes a stronger magnetic field.

D). No. The magnetic field isn't decreased. More current causes a stronger magnetic field.
