Hi there!

Recall the equation for the magnetic field of a wire (assuming infinite):

[tex]B = \frac{\mu _0 i_{encl}}{2\pi r}[/tex]

B = Magnetic field (T)
μ₀ = Permeability of Free Space (Tm/A)

i = enclosed current (A)
r = distance from wire (m)

From the equation, we can see that there is a DIRECT relationship between the current and the magnetic field.

Therefore, if the current is increased by a factor of 3, the FIELD will also be increased by a factor of three.
