Its magnetic domains line up.
When an iron bar is placed near a magnet, the magnetic field of the magnet aligns the magnetic domains within the iron bar. This alignment increases the overall magnetic field strength of the iron bar, effectively inducing magnetism in the bar.
Bar magnets interact with iron filings by creating a magnetic field that causes the iron filings to align along the magnetic field lines, forming patterns that show the shape and direction of the magnetic field.
The Earth's magnetic field is generated by the movement of molten iron in the outer core, while a bar magnet is a permanent magnet made of a material that can be magnetized, such as iron. The Earth's magnetic field is much weaker and more complex than that of a bar magnet, which has a consistent north and south pole.
The iron bar would become magnetized by induction through the wire coil. It would temporarily gain magnetic properties while in contact with the coil, but would lose them once removed.
When a bar magnet is placed under a sheet of paper with iron filings on top, the iron filings align along the magnetic field lines of the magnet, showing the direction and strength of the magnetic field.
align in the same direction, creating a magnetic field within the iron bar. This alignment occurs due to the interaction between the Earth's magnetic field and the magnetic properties of the iron, resulting in the iron bar becoming magnetized.

An iron bar is placed in a solenoid to increase the magnetic field strength produced by the solenoid. The iron bar becomes magnetized by the solenoid's magnetic field, enhancing the overall magnetic effect. This is commonly used in devices like electromagnets to amplify their magnetic strength.

Yes, an iron hinge is magnetic because iron is a ferromagnetic material, which means it can be magnetized. When exposed to a magnetic field, iron becomes magnetic and can attract or repel other magnetic materials.
Yes, iron screws are magnetic because iron itself is a magnetic material. This means that iron screws can be attracted to magnets and can themselves become magnets when exposed to a magnetic field.
It is made of a type of magnetic iron called magnetite.

You can differentiate between a bar of iron and a bar of copper by testing their magnetic properties - iron is attracted to magnets, while copper is not. A bar magnet will attract small iron objects, while a bar of copper will not be attracted.
