The equation $$\tau = \mu \times b$$ represents the torque experienced by a magnetic dipole moment $$\mu$$ in a magnetic field $$b$$. Torque is a measure of the force that causes an object to rotate about an axis, and in this context, it describes how a current loop or magnetic dipole interacts with an external magnetic field, leading to rotational motion. Understanding this relationship helps clarify the behavior of magnetic materials and devices under the influence of magnetic fields.
congrats on reading the definition of τ = μ × b. now let's actually learn it.
