What is the purpose of the soft iron core used in making an electromag...
Soft iron core is used to make electromagnets as it gains and losses magnetism quickly depending on existence of magnetic fields.... So, they get easily magnetised/demagnetised when current is flowing or not flowing along the solenoid...When the current passes through it, it gets instantly magnetized to generate a strong and dense magnetic field. Also, when the current is stopped as circuit breaks, it gets instantly demagnetized..Soft iron is said to form a temporary magnet.!!

It is used to make electromagnet as it has significant or high magnetic properties ..
it get magnetized when current I passed and demagnitized as current stops...

It is temporary magnet only work ....or show magnetic properties ...when current is supplied whereas permanent magnets never retain their magnetic behaviour..
