No. If the current passing through a conductor is increased, the strength of the magnetic field produced by the conductor also increases.

According to Ampere's law, the magnetic field strength (B) around a long straight wire is directly proportional to the current (I) flowing through the wire. Mathematically, it can be expressed as:

B ∝ I

Where:

B represents the magnetic field strength

I represents the current flowing through the conductor

Therefore, if the current (I) flowing through the conductor increases from 10 A to 15 A, the magnetic field strength (B) will also increase accordingly.
