The magnetic flux through a coil containing two loops changes at a constant rate from -58 Wb to +38 Wb in 0.34 s. What is the emf induced in the coil? Given: Solution: | | | | | | | | | | ( )| ( )| ( ) | | | | 2. The rectangular loop as shown in the figure below is being pushed to the right, where the magnetic field points inward. In what direction is the induced current? Explain your reasoning. The induced current must be in counter- clockwise direction. As the loop being pushed to the right, the magnetic field increased. To maintain its equilibrium, the loop must counteract the field. Using right-hand rule, the magnetic field will oppose the inward magnetic
