If the tent is flattened out on the table in 0.100 sec, what is the average induced emf in the wire during this time ?

is so that the magnet gets demagnetized when inside the solenoid The coercitivity of a small magnet where the ferromagnet gets demagnetized is 3× 10^3 A/m. The current required to be passed in a solenoid of length 10cm and number of turns 100 The wire as shown in figure is bent in the shape of a tent Using Lenz's law
