Web21 apr. 2024 · (8.4.1) E B = − μ → m ⋅ B → Magnets are acted on by forces and torques when placed within an external applied magnetic field (Figure 8.4. 2 ). In a uniform external field, a magnet experiences no net force, but a net torque. The torque tries to align the magnetic moment ( μ → m of the magnet with the external field B →. WebThe magnetic field strength 𝐵 at the center of a current-carrying loop of wire is given by the equation 𝐵 = 𝜇 𝐼 2 𝑟, where 𝐼 is the current in the loop, 𝑟 is the radius is the loop, and 𝜇 is the permeability of free space, often expressed as 4 𝜋 × 1 0 T⋅m/A.
