Development (20 - 25 minutes)

1. Theory of Faraday’s Law (7-10 minutes):

   • The teacher will introduce Faraday's Law, emphasizing that it is a basic principle of electromagnetism that explains how a change in the magnetic field within a loop of wire induces an electric current in the wire.
   • The teacher will explain the formula for Faraday's Law: the magnitude of the induced EMF (Electromotive Force) is directly proportional to the rate of change of magnetic flux. This can be written as: E = -dPhi/dt, where E is the induced EMF, dPhi is the change in magnetic flux, and dt is the change in time.

   • The teacher will explain that Faraday's Law is crucial in understanding the relationship between electricity and chemistry. They will illustrate this by discussing the process of electrolysis.
   • The teacher will use diagrams and animations to show the setup for electrolysis, with two electrodes (an anode and a cathode) submerged in an electrolyte. The teacher will explain how, when a voltage is applied, the positive ions move towards the cathode, gaining electrons and getting reduced, and the negative ions move towards the anode, losing electrons and getting oxidized.
   • The teacher will then relate this process to Faraday's Law, explaining that the amount of substance produced or consumed at an electrode during electrolysis is directly proportional to the number of electrons transferred in the overall balanced chemical equation, which is consistent with Faraday's Law.
   • The teacher will discuss further examples of chemical reactions that are driven by electricity, such as the charging and discharging of batteries and the process of electroplating.

3. Applications of Faraday’s Law (6-8 minutes):

   • The teacher will now discuss the various applications of Faraday's Law in real-world scenarios, especially in industries.
