Explain the principles of electromagnetic induction and its applications in various technologies. Discuss Faraday’s and Lenz’s laws and how they govern the generation of electric currents through changing magnetic fields. Illustrate the working principles of devices such as generators, transformers, and induction cooktops, and analyze the efficiency and limitations of electromagnetic induction in practical engineering contexts.”

Magnetism – A Virtual PhET Lab
After completing this lab activity, the students should be able to:
Conduct an experiment to determine the magnetic field generated by a current-carrying wire loop
Calculate the magnetic field generated by a current-carrying wire loop
Write a lab report
Lab Report
The lab report must include the following:
Title
Introduction
Experimental Details or Theoretical Analysis
Results
Discussion
Conclusions and Summary
References
Lab Activity
Please follow the steps given below to conduct the experiment:
This lab requires you to produce a lab report to determine “Magnetic Field in a Current-Carrying Wire Loop.” This is the “Title” of your lab report.
Read the relevant chapter on magnetism and add an “Introduction.”
You conduct this lab by connecting to the PhET website by clicking on the link given below (or where applicable through the embedded simulation on the lab page):
Once you open the simulation, select “Electromagnet.” Then, please check all the boxes on the simulation page. Follow the lab scenario given to produce the lab report. All movements and tools you use in this simulated experiment will form the “Experimental Details” section of the lab report. You must keep a record of all the values appearing on the screen as experimental values for the scenario. These values also form part of the “Results” section of the lab report. Now, complete the theoretical calculations. These calculated values also form the “Results” section of the lab report.
Now, you can complete the “Discussion” section of your lab report by discussing the values and any other information relevant to the experiment.
Complete the lab report by adding a summary to the “Conclusion” section of your lab report
Lab Scenario
Find the radius of the wire loops in the simulation by using an appropriate equation. Please confirm the radius of the wire loops by conducting the experiment at least for three different loops.
Note that you can obtain the Magnetic Field Strength at the center of the loop by using the Field Meter. Make sure to keep the voltage to 10V and assume the current as 3 A. The permeability of free space value as 4pi X 10-7 T m/A.
High-voltage power is often carried in wire bundles made up of individual strands. In your initial post to the discussion, discuss the forces on the strands of wire due to the current flowing through them. What would happen if the force acted the opposite of the known behavior? Provide a detailed description.
Consider a piston-cylinder assembly in which a gas undergoes a cycle consisting of the following three processes Process 1-2: constant pressure, P= 1.4 bar, aL1 = 0.058 m3, W12 = 7.5 Id Process 2-3: Compression with PV= constant, U3 = U2 Process 3-1: Constant volume, U1 -U3 = -12.6 Id Neglect changes in kinetic or potential energy. (a) sketch the cycle on a P-V diagram, (b) calculate the net work for the cycle (in 1(1), and (c) calculate the heat transfer for the process 1-2 (in kJ). (Hint: Watch “Thermo Cycle Example”)
