NEET Physics Bar Magnet MCQ Question
Which of the following statements about a bar magnet and its interaction with a magnetic field are correct?
The magnetic moment of a bar magnet is maximum when aligned with the magnetic field.
A bar magnet experiences maximum torque when its axis is perpendicular to the magnetic field direction.
Work is done by an external torque to turn the magnet from alignment with the field to normal position.
The torque on a bar magnet is zero when it is opposite to the direction of the magnetic field.
Correct Answer
Detailed Explanation
The NCERT context indicates that a bar magnet experiences maximum torque when perpendicular to the magnetic field (as it aligns itself). The magnetic moment being maximum in alignment and the work done in other positions do not hold true in this context.
