| 3. | (a), (b) | 4. | (c), (e) |
Which one of the following is correct?
| 1. | The magnetic field lines also represent the lines of force on a moving charged particle at every point. |
| 2. | The magnetic field lines can be entirely confined within the core of a toroid, but not within a straight solenoid. |
| 3. | A bar magnet exerts a torque on itself due to its own field. |
| 4. | The magnetic field arises due to stationary charges. |
