What is the effect of doubling the distance from a long straight wire on the magnetic field strength?

What is the effect of doubling the distance from a long straight wire on the magnetic field strength?

Step 1: Understand that a long straight wire creates a magnetic field around it.
Step 2: Know that the strength of this magnetic field depends on the distance from the wire.
Step 3: Learn about the Biot-Savart Law, which tells us how the magnetic field strength changes with distance.
Step 4: Remember that the magnetic field strength is inversely proportional to the distance. This means that as the distance increases, the magnetic field strength decreases.
Step 5: If you double the distance from the wire, the magnetic field strength becomes half of what it was before.
