Give a more general expression for the magnitude of the torque T. Rewrite the answer found in Part A in terms of the magnitude of the magnetic dipole moment of the current loop m.

Give a more general expression for the magnitude of the torque T. Rewrite the answer found in Part A in terms of the magnitude of the magnetic dipole moment of the current loop m. Define the angle between the vector perpendicular to the plane of the coil and the magnetic field to be ф, noting that this angle is the complement of angle θ in Part A.

Give your answer in terms of the magnetic moment m, magnetic field B, and φ .

Expert Solution

In the second figure, you may notice that the angle between the magnetic field B and magnetic moment m is .

As, torque is define as the product of force to the perpendicular distance. So, resolving me into two components will be give one with sin and other one with cos.

Therefore,the general expression for this problem is

The torque (T) that is exerted on a magnetic dipole moment (μ) depends on the orientation of the magnetic dipole moment. Rank the three loops of wire carrying current shown in (Figure 4) in order by the magnitude of the torque exerted on them. Rank the magnitude of the torque exerted on the loops from greatest to least. If two loops have the same magnitude of torque, place one on top of the other.
