What Types of Magnets Are Produced by Running Electric Current through a Soft Iron Core?

Answer

When electricity is ran through a soft iron core, it creates an electromagnet. When the current from the electricity is stopped, the iron core loses it magnetic field.
1 Additional Answer
Soft iron cores are commonly used to make electromagnets, due to their ability to create 50,000 times the magnetic field of an air core electromagnet. Soft iron is also used because it stops being magnetic with the current stops, unlike hard iron that stays magnetized.
