why is a horseshoe magnet made of soft iron bar

  • Magnetic Shielding

    Magnetic Shielding. There is no known INSULATOR for magnetic flux. If a nonmagnetic material is placed in a magnetic field, there is no appreciable change in flux - that is, the flux penetrates the nonmagnetic material.For example, a glass plate placed between the poles of a horseshoe magnet will have no appreciable effect on the field although glass itself is a good insulator in …

  • Why are electromagnets made of soft iron? | Socratic

    2015-4-17 · This is because soft iron has the property of losing its magnetism(or is able to be demagnetized) very quickly. An electromagnet works in this way: when current flows through it, it becomes magnetized, and immediately current stops flowing, it loses its magnetism. Hence, soft iron cores are the ideal material for this application.
