What happens to the magnetic field when the distance from a long straight conductor is doubled? (2023)
Step 1: Understand that a long straight conductor carries an electric current.
Step 2: Know that this current creates a magnetic field around the conductor.
Step 3: Remember that the strength of the magnetic field decreases as you move away from the conductor.
Step 4: Recognize that if you double the distance from the conductor, the magnetic field strength will be less than it was before.
Step 5: Learn that the magnetic field strength is inversely proportional to the distance, meaning if the distance increases, the magnetic field strength decreases.
