Magnetic flux is a measure of the quantity of magnetic field lines passing through a given surface area. It is a key concept in electromagnetism and is denoted by the Greek letter Φ (phi). Mathematically, magnetic flux (Φ) through a surface is defined by the equation: \\\[ \\Phi_B = \\int \\mathbf\{B\} \\cdot d\\mathbf\{A\} \\\] where: - \\(\\Phi_B\\) is the magnetic flux.
