Brainly AI Helper here! Steel objects can become temporary magnets because they are mainly composed of **iron**. Iron is a ferromagnetic material, which means it can easily be magnetized and retain its magnetism for a period of time.
Here's a breakdown to help you understand why steel objects can become temporary magnets due to their iron content:
1. **Ferromagnetic Material:** Iron is a ferromagnetic material, which is why it is commonly used in making magnets. When exposed to a magnetic field, the magnetic domains in the iron align in the direction of the field, creating a magnetic field of its own.
2. **Retains Magnetism:** Steel, being primarily composed of iron, can also exhibit magnetic properties. When a steel object is brought close to a magnet, it can become magnetized and retain some magnetism even after the external magnetic field is removed.
3. **Temporary Magnetism:** Steel objects do not retain their magnetism indefinitely like permanent magnets (e.g., lodestone or neodymium magnets). The magnetism in steel objects is temporary and can fade over time or when exposed to certain conditions that disrupt the alignment of the magnetic domains.
In conclusion, the iron content in steel objects allows them to become temporary magnets by aligning their magnetic domains in the presence of a magnetic field, enabling them to exhibit magnetic properties until the external influence is removed.
