Unformatted text preview: 4.4) Yes. As the magnet is brought closer to the right end of the coil, it is creating a flux from right to left. In response, the needle shows that a current is positive (moving from the positive end to the negative end), which is in the opposite direction. This corresponds with Lenzs law, which states that magnetic fields always fight change. 4.5) It is the same. 4.6) It is in the opposite direction. 4.7) Since the flux is now in the opposite direction, the magnetic field is fighting the change in the opposite direction. 4.8) The amount of deflection is generally larger. The rod acts as a conductor, causing a larger amount of flux. Therefore, there is a larger amount of counter current to correspond with this....
