It will happen in any magnetic field if the iron rod is aligned with the external flux lines and you hammer in the direction of the flux lines, and you have LOTS of patience as you may need to hammer a hundred or more times to get a "strong" magnetization.
What happens (if you want to know) is the hammering joggles the magnetic domains from their previous random orientations and they gradually settle into orientations more closely aligned with the external flux lines.
The same thing will happen but more effectively if the iron rod is heated to its curie point temperature and then cooled while aligned with the external flux lines. The heat allows all the magnetic domains to realign.
The earths magnetic field results from deep in the earths core. Magnetic conduction from within the earths core is believed to be the cause of this.
earths magnetic field is generated by the circulation of liquid metal.
Scientists believe that it is the movements in the liquid outer core that create the magnetic field. Earth's magnetic field affects the whole planet.
No, a magnetic field is induced by moving electric charges. If a ferrous material (one containing iron) is placed in a magnetic field, the individual magnetic dipoles can be aligned in accordance with the magnetic field. Since the molten iron in the earth's core carries charges, a magnetic field is induced around the earth (with field lines coming OUT of the south pole and into the north). This magnetic field can align magnetic dipoles just as any man-made electromagnet can.

A magnetic field.
Earth's magnetic field created by earths magnets deflects cosmic rays which damage our biosphere.
Yes, all magnets have a magnetic field. When a material becomes magnetized, it creates a magnetic field around itself that attracts or repels other materials. This magnetic field is the reason why magnets can exert force on other magnets or magnetic materials.
Any magnet will always align itself to north south direction of earths magnetic field. Magnetic needle will always be perpendicular to the direction of current. Stronger magnets attracts weak magnets towards itself if the weak magnet is placed in stronger magnets magnetic field.
I am not entirely sure what you are after, but you might say that:* It is the nature of magnets to be magnetic. Or:* It is the nature of magnets to be surrounded by a magnetic field.
Temporary magnets and permanent magnets are alike in that they both produce a magnetic field and can attract materials containing iron. However, temporary magnets only exhibit magnetic properties when exposed to a magnetic field, while permanent magnets retain their magnetism without the need for an external magnetic field.
Yes, the magnetic field strength will increase if there are more magnets because the magnetic fields generated by individual magnets add up. This is known as superposition, and the resultant field becomes stronger as more magnets are brought together.
When you add multiple magnets, the magnetic fields combine according to the principles of superposition. If the magnets are aligned in the same direction, the magnetic field strength increases and extends further. If the magnets are aligned in opposite directions, they can cancel out each other's magnetic fields.
The magnetic field strength of neodymium magnets is typically around 1.3 to 1.4 tesla, which is significantly stronger than other types of magnets.
they combine and become one magnetic field
The stronger the magnetic field is.
Compass magnets align themselves with Earth's magnetic field due to their own magnetic properties. Electromagnets, like the one found in devices such as phones or microwaves, can create magnetic fields that may interfere with a compass's accuracy if they are strong enough and placed close to the compass.
