Question

A student wants to test the force of magnetism by placing objects on top of a piece of cardboard and then moving them with a magnet placed under the cardboard. Which items will help the student with this investigation?

Answer 1

Any material that has ferromagnetic property

Step-by-step explanation:

Materials such as iron, nickel or cobalt are ferromagnetic element as they behave as small magnets in the presence of moving electric charge or static magnetic field.

When an external magnetic field is applied these ferromagnetic material align in a way that they contribute to produce a stronger magnetic field in the material and remain aligned even after removal of the external magnetic field.
