Why are magnetic field lines around a straight conductor denser near the wire and sparser with distance?

Subject: General Awareness | Topic: Science | Difficulty: MEDIUM

Options

1. (A) Because magnetic field strength decreases with distance from the wire
2. (B) Because interference occurs only due to external magnets
3. (C) Because the current flowing in the wire decreases with distance
4. (D) Because the magnetic field becomes uniform with distance

Verified Answer

Option (A): Because magnetic field strength decreases with distance from the wire
