What happens to the magnetic field strength if the distance from a long straight conductor is doubled?
It doubles
It halves
It quadruples
It becomes zero
The magnetic field strength around a long straight conductor is inversely proportional to the distance from the conductor. Therefore, if the distance is doubled, the magnetic field strength halves.

Q: What happens to the magnetic field strength if the distance from a long straight conductor is doubled?
Solution: The magnetic field strength around a long straight conductor is inversely proportional to the distance from the conductor. Therefore, if the distance is doubled, the magnetic field strength halves.
Steps: 5
Step 1: Understand that a long straight conductor creates a magnetic field around it.
Step 2: Know that the strength of this magnetic field depends on the distance from the conductor.
Step 3: 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 4: If the distance from the conductor is doubled, it means you are moving further away from it.
Step 5: Since the distance is doubled, the magnetic field strength will be halved.
