Question:
The coercivity of a small magnet where the ferromagnet gets
Last updated: 6/13/2023
The coercivity of a small magnet where the ferromagnet gets demagnetized is 3 x 10 A m 1 The current required to be passed in a solenoid of length 10 cm and number o turns 100 so that the magnet gets demagnetized when inside the solenoid is O 30 mA O 60 mA O 3 A 06 A
