The figure illustrates magnetic field lines generated by a magnet. Three points \(F,G,\) and \(H\) are marked in the magnetic field. Based on the pattern of field lines shown in the figure, what is the correct relationship among the magnetic field strengths \(B_F, B_G\) and \(B_H\) at these three points?
| 1. | \(B_F>B_G>B_H\) | 2. | \(B_F<B_G<B_H\) |
| 3. | \(B_F=B_H<B_G\) | 4. | \(B_F=B_H>B_G\) |

Magnetic lines of force due to a bar magnet do not intersect because
| 1. | a point always has a single net magnetic field |
| 2. | the lines have similar charges and so repel each other |
| 3. | the lines always diverge from a single force |
| 4. | the lines need magnetic lenses to be made to interest |

Given below are two statements:
| Statement I: | The magnetic field of a short bar magnet points from the south-pole to the north-pole within the bar magnet. |
| Statement II: | Bar magnets are made of ferromagnetic materials, and the magnetic field within is much stronger than that outside. |
| 1. | Statement I is incorrect and Statement II is correct. |
| 2. | Both Statement I and Statement II are correct. |
| 3. | Both Statement I and Statement II are incorrect. |
| 4. | Statement I is correct and Statement II is incorrect. |
