True or false? A piece of soft iron is permanently magnetised when placed near a magnet.
Question
True or false?
A piece of soft iron is permanently magnetised when placed near a magnet.
Solution
True or False?
The statement is False.
Explanation
Soft iron is a type of ferromagnetic material that can be magnetized, but it does not retain its magnetism once the external magnetic field is removed. When a piece of soft iron is placed near a magnet, it will become magnetized temporarily due to the influence of the magnetic field. However, once the external magnetic field is no longer present, the soft iron will quickly lose its magnetization.
In contrast, hard magnetic materials (like steel) can be permanently magnetized and retain their magnetism over time. Therefore, while soft iron can become magnetized in the presence of a magnetic field, it cannot be permanently magnetized, making the statement false.
