**Question 4:**Use Lenz’s law to determine the direction of the induced currents (if present) and mark them on the loops in the diagrams for the following situations:**Diagrams:**(a) A loop is near a magnetic field represented as a dashed oval next to a bar magnet (SM), with the magnet moving away from the loop marked with an arrow.(b) A loop with arrows pointing to the right, labeled "B = 0" in the background, and "move loop into B ≠ 0".(c) A loop with a constant current "I" flowing through a wire alongside the loop. An arrow indicates the motion direction of the loop marked "I constant".(d) A loop with arrows forming a circle in a magnetic field marked with X's in the background. The note reads "loop gets smaller" and "B".(e) A loop with two regions of opposing magnetic fields (dots and X's) labeled "Change directions of B". The note reads "B₀" near the loop and "W = 0".**Question 5:**A transformer with 1500 turns in the primary and 300 turns in the secondary is used to reduce the primary (input) voltage amplitude from 170V to that needed by the device. The current in the secondary coil has an amplitude of 3.2 A.(a) Is this a step-up or step-down transformer?(b) What is the voltage amplitude in the secondary coil?(c) What is the current amplitude in the primary coil?(d) What is the maximum power rating of the transformer?

Bar Magnet

In physics, magnetism is a phenomenon exhibited by a magnetic substance that exerts either attractive or repulsive force. A bar magnet is either a rectangular or round and hollow fit comprised of ferromagnetic materials and has a fanciful attractive field surrounded by it.
