Answer 1

A. When it is in a magnetic field, it becomes a temporary magnet.

Step-by-step explanation:

An iron bolt is attracted to a magnet because when in a magnetic field, the iron becomes a temporary magnet.

This is because the iron aligns their electrons in the magnetic fields.

• This causes that attraction between the magnet and the iron.
• Metals like iron are said to be ferromagnetic
• Unpaired electrons in iron spin in such a way that they align with the magnetic fields of the magnet.
