How is an unmagnetized piece of iron different from the same piece of iron when it is magnetized?
An unmagnetized piece of iron has its atoms pointing in different directions, and opposing each other. When the iron is magnetized, the atoms are mostly pointing in the same direction, and the fields add together.
What weighs more gold or diamonds?
Gram for gram, all things that weigh one gram weigh one gram, so one gram of diamonds weighs the same as one gram of gold.
How can a piece of iron be temporarily magnetized?
A piece of iron can be temporarily magnetized by stroking it with a magnet in the same direction multiple times. This aligns the magnetic domains within the iron, creating a temporary magnetic field. Charging the iron by induction, where it is brought close to a strong magnet, can also temporarily magnetize it.
Which is lighter 1kg of gold or 1kg of iron?
1kg of gold and 1kg of iron weigh the same amount because they both weigh 1 kilogram. The difference between the two lies in their density and value, not in their weight.
Why does a piece of iron feel colder than a piece of wood even though they are both in the same temperature?
Wood is a porous material in which a lot of air is trapped, and as a result, it is a poor conductor of heat. Iron is a denser material which is a good conductor of heat. So when you touch iron, heat flows easily from your finger into the colder piece of iron. Heat flows much more slowly from your finger into a piece of wood, even if the wood is exactly the same temperature as the iron.
Would a 10g piece of aluminum and 10g piece of iron have the same volume?
Of course not...different densities, different volumes per same weight.

What are the disadvantages of having iron armor?
The hardness and tensile strength provided by iron armor in comparison to its weight. The same hardness and/or tensile strenght can be matched or beaten by lighter alloys.

Is the queen sized blanket the same dimensions as the full sized blanket?
A queen sized and full sized blankets have the same dimensions.
What happens to the domains in a piece of iron when it becomes magnetised?
The iron automatically divides into domains separately. It does not exist in a state when magnetization occurs in the same direction, in the entire material. This is to minimize its internal energy.

What is a small region in a piece of iron where atomic magnetic line up in the same direction?
A small region in a piece of iron where atomic magnetic moments align in the same direction is called a magnetic domain. These domains can be influenced by external magnetic fields and can change their orientation, affecting the overall magnetization of the material.
How can a piece of iron be induced into becoming magnetized?
A piece of iron can be induced to become magnetized by placing it in a magnetic field. The magnetic field aligns the magnetic domains within the iron, creating a net magnetic field in the same direction as the applied field. Once the external magnetic field is removed, the iron will retain some level of magnetization.
This reaction occurs more quickly when powdered iron is used instead of a single piece of iron of the same mass because the powdered iron?
A reaction occurs more quickly when powdered iron is used instead of a single piece of iron of the same mass because the powdered iron has a much greater surface area and all chemical reactions take place on surfaces.
