The magnetic field lines of a bar magnet may NOT be drawn using:

Correct option is D

The correct answer is: (D) Wood particles

• Wood particles do not interact with the magnetic field lines, so they cannot be used to visualize or detect magnetic fields.
• Magnetic field lines are typically visualized using materials that respond to magnetic fields, such as iron filings, a magnetic compass, or another bar magnet.

Information Booster:

• Another bar magnet: it has its own magnetic field, and the field lines of one magnet can interact with another.
• A magnetic compass: A magnetic compass aligns with the magnetic field lines and can be used to determine the direction of the magnetic field.
• Iron filings: Iron filings align with the magnetic field lines and can be used to visually show the pattern of the magnetic field.
