Answer:

The orientation b has the largest magnetic torque.

Explanation:

As the complete question is not given, the complete question is attached herewith

From the diagram

[tex]|\mu_a|=|\mu_b|=|\mu_c|=|\mu|[/tex]

Also the angles for the 3 orientations are given as

[tex]\theta_a>90\\\theta_b=90\\\theta_c<90\\[/tex]

Now as the torque τ is given as

[tex]\tau=|\mu||B|sin\theta[/tex]

As the value of μ and B is same so value of τ is maximum for sin θ is maximum so

[tex]sin \theta_{max}=1\\\theta_{max}=90[/tex]

So the orientation b has the largest magnetic torque.

The orientation with the largest magnetic torque on the dipole is Orientation B (See attached image).

The torque on the dipole is defined as:

τ = µ×B,

where B is the external magnetic field.

The magnitude of this torque is µB sinθ, where θ is the angle between B and µ

Magnetic Torque is highest when;

→ →

µ ⊥ β

That is when θ = 90°. Hence B is the correct answer. Please see attached image.
