The magnetic field lines around a standard bar magnet go from:

• A. North to South
• B. South to North
• C. They form no pattern
• D. They exit both ends separately

Answer: (C)

Magnetic field lines form closed loops. Around a bar magnet, they emerge from the North end, curve through the surrounding space, and enter the South end. Inside the magnet, the direction reverses, continuing from South toward North, so every line completes a continuous loop. This looping pattern shows how the field wraps around the magnet and why the outside field goes from North to South while the inside goes from South to North. The notion of no pattern would ignore these continuous, curved lines that illustrate the field’s direction and strength.
