If the strength of electric current in a circular loop increases, does the magnetic field produced due to the current increase?

If the strength of electric current in a circular loop increases, does the magnetic field produced due to the current increase ?

When temperature of metal increases, does the resistance increases or decreases?

Electric current, if very weak, does not produce magnetic field.

If current in the core decreases, the strength of the magnetic field

The strength of a magnetic field increases as _________
