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.
