Question: During a demonstration in our classroom, I hold a big magnet right under the big table pointing North Pole up. When I lower the magnet the magnetic field strength decreases from a value of 0.728 T to 0.150 T uniformly in 0.238 s.
Part A: If a metal loop with an area of 0.450 m2 is laying flat on the table during the demonstration, what is the induced emf in the loop?
Rework your solution from the beginning and check each step carefully.
