WebMagnetic flux is a scalar quantity and its positive/negative sign indicates the direction of the magnetic field. And the Faraday's law of induction is a quantitative version of Lenz's law, which may help your understanding: ∮ … WebAlthough the stationary magnet might produce a large magnetic field, no EMF can be induced because the flux through the coil is not changing. When the magnet moves closer to the coil the flux rapidly increases until the magnet is inside the coil. As it passes through the coil the magnetic flux through the coil begins to decrease.
