What happens to the magnetic field strength when the distance from a long straight conductor is doubled?

What happens to the magnetic field strength when the distance from a long straight conductor is doubled?

Step 1: Understand that a long straight conductor (like a wire) creates a magnetic field around it when electric current flows through it.
Step 2: Know that the strength of this magnetic field depends on the distance from the wire.
Step 3: Remember the rule: the magnetic field strength decreases as you move away from the wire.
Step 4: When you double the distance from the wire, the magnetic field strength is affected.
Step 5: Specifically, the magnetic field strength becomes weaker by half (it is inversely proportional to the distance).
Step 6: Therefore, if you double the distance, the magnetic field strength is halved.
