To find the magnetic field due to a dipole at a given point, we can use the formula for the magnetic field \( B \) due to a magnetic dipole moment \( m \): \[ B = \frac{\mu_0}{4\pi} \cdot \frac{2m \cos \theta}{r^3} \] where: - \( \mu_0 \) is the permeability of free space, approximately \( 4\pi \times 10^{-7} \, \text{T m/A} \) ...
