Question
Which of the following cannot produce a uniform magnetic field?
- A bar magnet
- Two bar magnets
- Horseshoe magnet
- Both B and C
Hint:
A bar magnet
The correct answer is: A bar magnet
A bar magnet produces a non uniform magnetic field that can be seen by the magnetic lines of force arising from the north pole of the magnet and progressing towards the south pole of the magnet. For a non uniform magnetic field, the magnetic field lines are not equally spaced and parallel, but are either converging or diverging.
