Please help im really bad at physics any help is appreciated!
Q1:Explain the mechanism by which AC (alternating current) through the primary circuit of a transformer produces an alternating voltage and current in the secondary coil. Then explain why this would or would not work with DC (nonalternating current) in the primary coil

Q2:Explain briefly how moving electric charges at an atomic level produce magnetically polarized domains in a sample of iron, and how the domain structure differs for a magnetized iron bar and one that is not magnetized.
