Students often treat magnetic poles as real physical entities, but they are only a convenient abstraction; there are no isolated magnetic charges, so poles are mathematical constructs.

Pick the correct options.

Multiple Choice Options

  • A Magnetic field is produced by electric charges only
  • B Magnetic poles are only mathematical assumptions having no real existence
  • C A north pole is equivalent to a clockwise current and a south pole is equivalent to an anticlockwise current.
  • D A bar magnet is equivalent to a long, straight current.

Step-by-Step Verified Solution

**Answer:** (b) Magnetic poles are only mathematical assumptions having no real existence. **Step-by-Step Explanation:** Magnetic monopoles do not exist. Poles are mathematical constructs.
