Answer

Brief Explanations:

The strength of the magnetic field around a current - carrying wire is given by Ampere's law. The magnetic field strength $B$ is directly proportional to the current $I$ and inversely proportional to the distance $r$ from the wire ($B=\frac{\mu_0I}{2\pi r}$, where $\mu_0$ is the permeability of free - space). The type of metal affects resistance but not directly the magnetic field strength. The direction of the current affects the direction of the magnetic field, not its strength. The temperature of the wire affects resistance and current to some extent but not as directly as the current and distance.

Answer:

the amount of the current, the distance from the wire
