The bar magnet illustrated in the diagram above picks up an unmagnetised steel nail X. In turn, X picks up a similar nail Y and so on. The nail are said to be magnetised by
Answer Details
The nail X is picked up by the bar magnet because of the magnetic field produced by the magnet. When nail X comes into contact with nail Y, it induces a temporary magnetism in nail Y due to the magnetic field of nail X. This temporary magnetism in nail Y allows it to attract another similar nail Z, and the process continues.
The process by which nail X magnetizes nail Y is called "induction." Induction is the process by which a magnetic field induces a magnetic field in a nearby object without physical contact. In this case, the magnetic field of nail X induces a temporary magnetic field in nail Y, making it temporarily magnetized.
Therefore, the nails are magnetized by induction. The correct answer is.
