Which one of the following material is most suitstble for making core of an electromagnet?
Correct answer: D. Soft iron
- A. Air
- B. Steel
- C. Cu-Ni alloy
- D. Soft iron
Explanation
Determining the Most Suitable Material for an Electromagnet CoreSoft iron is a material widely used for making the core of an electromagnet due to its high magnetic permeability. It easily magnetizes and demagnetizes, making it suitable for applications requiring rapid changes in the magnetic field. Soft iron loses its magnetism when the external magnetic field is removed, making it a suitable choice for electromagnet cores.### Correct Answer:Soft iron is the most suitable material for making the core of an electromagnet due to its high magnetic permeability and ability to magnetize and demagnetize easily.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
