Question 1.
What is the formula for torque on a magnetic dipole in a magnetic field?
Show hintHide hint
Think about how a force applies on an angle.
Question 2.
What is potential energy when a magnetic dipole aligns with the magnetic field?
Show hintHide hint
Review the relationships between energy and position.
3Question 3.
What is the formula for torque on a magnetic dipole?
- A) τ = m · B
- B) τ = m × B
- C) τ = m/B
Show hintHide hint
Look for the interaction between force and rotation.
4Question 4.
True or False: A magnetic dipole has zero potential energy when aligned with the magnetic field.
- True
- False
Show hintHide hint
Consider energy implications depending on position.
Question 5.
A magnetic dipole with a magnetic moment of 3 A·m² lies in a uniform magnetic field of strength 0.4 T. What is the torque acting on the dipole when it is tilted at an angle of 60 degrees?
Show hintHide hint
Apply the torque formula while ensuring to assess (sin 60°).
Question 6.
Consider the magnetic potential energy of a dipole when it is positioned at 120 degrees relative to a uniform magnetic field of 0.5 T. If its magnetic moment is 2 A·m², calculate the potential energy.
Show hintHide hint
Remember to evaluate cos(120°) correctly for negative angles.
