Introduction:
The ratio of magnetic fields when a smaller bar magnet is in the end-on position to the broad-side position can be determined by analyzing the magnetic field lines and the orientation of the magnets. This ratio can help us understand the distribution and alignment of magnetic fields in different positions.
End-on Position:
In the end-on position, the smaller bar magnet is positioned with one of its poles facing towards the larger magnet. This means that the magnetic field lines of the smaller magnet are aligned with the magnetic field lines of the larger magnet. The magnetic field lines of both magnets reinforce each other, resulting in a stronger combined magnetic field.
Broad-side Position:
In the broad-side position, the smaller bar magnet is positioned with one of its sides facing towards the larger magnet. This means that the magnetic field lines of the smaller magnet are perpendicular to the magnetic field lines of the larger magnet. The magnetic field lines of the smaller magnet do not contribute to the magnetic field of the larger magnet. Therefore, the combined magnetic field is weaker compared to the end-on position.
Calculating the Ratio:
To calculate the ratio of magnetic fields, we need to compare the magnetic field strengths in the end-on and broad-side positions. Let's assume the magnetic field strength in the end-on position is B1, and the magnetic field strength in the broad-side position is B2.
Ratio of Magnetic Fields:
The ratio of magnetic fields can be calculated as B1/B2. From the above explanations, we know that the magnetic field is stronger in the end-on position compared to the broad-side position. This means that B1 > B2.
Final Answer:
Since B1 is greater than B2, the ratio B1/B2 is greater than 1. Therefore, the correct answer is d) 2.
Explanation:
In the end-on position, the magnetic field lines of the smaller magnet reinforce the magnetic field of the larger magnet, resulting in a stronger combined magnetic field. However, in the broad-side position, the magnetic field lines of the smaller magnet do not contribute to the magnetic field of the larger magnet, resulting in a weaker combined magnetic field. Hence, the ratio of magnetic fields in the end-on position to the broad-side position is 2.
