Question

which of the following objects could be turned into a temporary magnet? a glass tube an iron nail a silver ring

Explanation:

A temporary magnet is typically made from a ferromagnetic material. Iron is a ferromagnetic material, while glass (a non - metal) and silver (a non - ferromagnetic metal) are not. When an iron nail is exposed to a magnetic field (e.g., by being near a permanent magnet), its magnetic domains can align, making it a temporary magnet. Once the external magnetic field is removed, it may lose most of its magnetism (though some residual magnetism may remain depending on the conditions).

Answer:

B. An iron nail
