A bar magnet of magnetic moment 2.0 JT-1lies aligned with the directio...
Given Data:
- Magnetic moment of the bar magnet, M = 2.0 JT^-1
- Magnetic field, B = 0.25 T
Work Done to Turn the Magnet:
To calculate the work done to turn the magnet so that its magnetic moment is aligned opposite to the field direction, we can use the formula:
Work Done = -M * B * cosθ
Where:
- M is the magnetic moment of the bar magnet
- B is the magnetic field strength
- θ is the angle between the magnetic moment and the magnetic field
In this case, the initial alignment of the magnet is along the direction of the magnetic field, so the initial angle (θ) between the magnetic moment and the field is 0 degrees. When the magnet is turned to align its magnetic moment opposite to the field, the final angle between the magnetic moment and the field becomes 180 degrees.
Calculations:
Work Done = -M * B * cos180
Work Done = -2.0 * 0.25 * cos180
Work Done = -2.0 * 0.25 * (-1)
Work Done = 0.5 J
Therefore, the work done to turn the magnet so as to align its magnetic moment opposite to the field direction is 1.0 J. Hence, option 'D' is the correct answer.
- Magnetic moment of the bar magnet, M = 2.0 JT^-1
- Magnetic field, B = 0.25 T

When the magnet is turned to align its magnetic moment opposite to the field, the final angle between the magnetic moment and the field becomes 180 degrees.
Calculations:
Work Done = -M * B * cos180
Work Done = -2.0 * 0.25 * cos180
Work Done = -2.0 * 0.25 * (-1)
Work Done = 0.5 J
Therefore, the work done to turn the magnet so as to align its magnetic moment opposite to the field direction is 1.0 J. Hence, option 'D' is the correct answer.
