A meter shows the direction and magnitude of the current. View the magnetic field lines or use a meter to show the direction and magnitude of the current. You can also play with electromagnets, … WebFARADAY'S LAW. Conceptually, Faraday's Law tells us that changing magnetic fields induce electric fields. Mathematically, this law states that the emf E — the integral of the electric field around a closed path — is equal to the change in magnetic flux Φ through the path: E = ∫E ⋅ dl = − dΦ / dt, where. Φ = ∫B ⋅ dA.
