Question

why coiled wire magnetic field line closer near the wire?​

Answer 1

Explanation:

However, the magnetic field around a coiled wire is stronger than the magnetic field around a straight wire. That's because each turn of the wire in the coil has its own magnetic field. ... Increasing the amount of current flowing through the coil also increases the strength of the magnetic field.
