Respuesta :
The soft iron inside the coil makes the magnetic field stronger because it becomes a magnet itself when the current is flowing. Soft iron is used because it loses its magne
Answer:
Because of the high permeability and high saturation level of holding magnetism.
Explanation:
Soft iron always used in the core of an electromagnet because of the following reason which are discussed below.
- Permeability: These magnets are highly permeable means they can gain magnetism when current is passes through them and instantly loose magnetism after removal of current.
- High saturation level: The property of these soft magnets are they have the high value of saturation means they can hold high level of magnetism without easily saturating.
