**Problem-2 on Magnetic Force/Field/Flux/Faraday-Lenz' Law** **Given:** A single square coil consisting of four sections of copper wire (ab, bc, cd, da) with an equivalent resistance of 10 ohms is placed in an increasing magnetic field (\(\Delta B/\Delta t = 2.5 \, \text{T/s}\)) with direction into the screen as indicated by x. The area of the square, \(A = 9 \, \text{m}^2\). **Questions (6% each):** 1. Magnetic flux change rate, \(\Delta \Phi/\Delta t\) 2. Total emf induced in the coil, emf = ? 3. The induced current? 4. Electric power dissipation on the copper wire 5. The direction of induced current, clockwise or counter-clockwise? **Diagram Explanation:** The diagram shows a square coil placed in a magnetic field, with crosses ("x") indicating the direction of the magnetic field into the page. The square coil is outlined and sections are labeled as ab, bc, cd, and da. The setup demonstrates the application of Faraday-Lenz's law, which can be used to address the questions related to the magnetic flux change rate, induced emf, current, power dissipation, and direction of current.
