To practice Tactics Box 25.1
Using Lenz's law. Lenz's law is a useful rule for determining the
direction of the induced current in a loop. Specifically, it says
that there is an induced current in a closed conducting loop if and
only if the magnetic flux through the loop is changing. The
direction of the induced current is such that the induced magnetic
field opposes the change in the flux. The following Tactics Box
summarizes the essential steps in using...

faraday's law of electromagnetic induction says that if there is relative motion between any conductor and magnetic field an induced emf is induced in the conductor and if the conductor is cloesd loop then induced current will also start to flow. my question is that where are the points on the loop across which the potential difference generated so that current can flow, because the current flows only due to potential difference

Question7 1 pts Which statement is correct regarding Faraday's Law? O An emf is induced around a closed loop if there is a electric flux through the loop changes. The magnitude of the emf is proportional to the rate the electric flux changes with time. An emf is induced around a closed lool if the magnetic flux through the loop changes with position. The magnitude of the emf is proportional to the rate the magnetic flux changes with position O...

Learning Goal: To understand the terms in Faraday's law and to be able to identify the magnitude and direction of induced emf. Faraday's law states that induced emf is directly proportional to the time rate of change of magnetic flux. Mathematically, it can be written as E=???B?t, where E is the emf induced in a closed loop, and ??B?t is the rate of change of the magnetic flux through a surface bounded by the loop. For uniform magnetic fields the...
