Answer 1

1. Magnitude of current.
2. No. of turns.

Answer 2

A current carrying wire generates a magnetic field. According to Biot-Savart's law, the magnetic field at a point due to an element of a conductor carrying current is, Directly proportional to the strength of the current, i. Directlyproportional to the length of the element, dl.
