The strength of a magnetized iron rod can be increased by enhancing its magnetic properties through several methods. One effective approach is to increase the number of turns in a coil wrapped around the rod and pass a higher electric current through it, which amplifies the magnetic field. Additionally, using materials with higher magnetic permeability or heating the rod and cooling it in a magnetic field can also improve its magnetization. Finally, reducing impurities and optimizing the rod's shape can help maximize its magnetic strength.
An iron rod can be magnetized using the electrical method by wrapping a wire around the rod and passing an electric current through the wire. This creates a magnetic field around the rod, aligning the magnetic domains within the iron to become magnetized. The strength of the magnetic field can be controlled by changing the amount of current flowing through the wire.
If you place a steel rod inside a solenoid instead of an iron one, the magnetic field strength will still increase, but not as significantly as with an iron rod. Steel is a ferromagnetic material, but its magnetic permeability is generally lower than that of iron, leading to a weaker magnetic response. Consequently, while the steel rod will still enhance the magnetic field, its effectiveness will be reduced compared to an iron rod.
If the rod is made from pure iron it is not a mixture.
Graphics can't be shown on Answers.com. Take a large iron nail (or several nails, 6 inches long). Wrap several layers of thinly insulated wire round the nail(s), and connect the bared ends of the wire to the positive and negative terminals of a 9 volt battery. As the electrical current is sent through the coiled wire, the iron nail(s) becomes electro-magnetised and will attract metal. Turn the current off, and the metal will drop off, for the nail(s) are no longer magnetised.
Iron rod is a conductive material. You will get electrocuted if you touch a live wire with any conductive material like iron rod. It could be fatal to do so.

Increasing the number of coils increases the strength of the magnetic field generated by the electromagnet. This stronger magnetic field can attract more paper clips to the iron rod because the field has a greater reach and force.
The phrase "a rope of sand" is used to describe something weak or easily broken, while "a rod of iron" symbolizes strength and durability. Therefore, in this context, "a rope of sand" is not better than "a rod of iron" as it signifies fragility and instability compared to the strength and resilience represented by "a rod of iron."
If the coil encloses an iron rod, then the magnetic field strength inside a current-carrying coil will be increased. This occurs because the air path in the coil is made shorter by putting in the rod. This in turn causes an increase in the field.
iron rod
When an iron rod is subjected to heat energy, the atoms within the rod start vibrating more rapidly, which results in an increase in temperature. This increased vibration causes the rod to heat up as the kinetic energy of the atoms is converted into thermal energy.

Steel is a ferromagnetic material, but its magnetic permeability is generally lower than that of iron, leading to a weaker magnetic response.

When an iron rod is inserted in the center of a solenoid, it is called an electromagnet. The iron core increases the magnetic field strength generated by the solenoid, making it more effective for various applications such as in electric motors or magnetic locks.

Heat cannot be transferred in this way with an iron rod because iron is a good conductor of heat. When the iron rod is held at one end and heat is applied to the other end, the heat energy will quickly travel through the iron rod, leading to a uniform temperature distribution along the rod.
