Explain why the object on the left is not magnetized while the one on the right is magnetized.
The non-magnetized object on the left has domains with magnetic fields pointing in all directions, while the magnetized object on the right has domains with the magnetic fields all pointing in the same direction.
The non-magnetized object on the left must be made out of a material other than iron, while the magnetized object on the right must be made out of iron.
The non-magnetized object on the left has to be plastic, while the magnetized object on the right has to be metal.
The non-magnetized object on the left is an electromagnet with the electric current turned off, while the magnetized object on the right is an electromagnet with the electric current turned on.
