Which has more force of attraction an iron nail a piece of chalk and a rubber band?
an iron nail
How does the force effect the shape of the hot piece of iron hammered by a blacksmith?
When a piece of iron is heated to red-hot or above, then the bonds between the molecules have been lengthened, and the relationship of these bonds to each other may be altered permanently. When the iron cools, the new molecular arrangement becomes set. You may experiment in a similar manner, with a piece of modelling clay. It will respond in a manner representative of hot iron.
Is the force of gravity stronger on a piece of iron than on a piece of wood if both have the same mass?
The gravity would stay the same. Weight and density has no effect on the gravitation on the object when on earth. Everything is pulled the same.
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.
Can electric field lines cross?
Lines of force don't exist. They can't cross each other because they aren't there. The common (related) demonstration of magnetic lines of force using iron filings works because of the fact that the iron filings become little magnets and line up head to tail. If you photograph them and re-run the experiment you will see that the lines are different, which shows that they are an "artifact" of the magnetic field. No actual lines exist.
Why a piece of chalk can be broken easily but iron cannot?
a chalk piece can be broken easily but not an iron piece because iron has greater intermolecular force of attraction which keeps the particles together . the strength of this force of attraction varies from one kind of matter to another
How do you find force of attraction?
You can take a piece of iron and magnetize it!

What characteristic exist in magnets that does not exist in material that lack magnetism?
A magnet is a piece of iron or other material that attracts other iron-containing objects. The characteristic that exists in magnets that does not exist in materials that lack magnetism is the alignment of domains.
What characteristic exist in magnets that does not exist in materials that lack magnetism?
One characteristic unique to magnets is their ability to attract or repel other magnets due to their magnetic field. This property arises from the alignment of electron spins within the material, creating a north and south pole. Materials lacking magnetism do not exhibit this behavior as their electron spins are randomly oriented.
A blacksmith hammers a hot piece of iron while making a tool how does the force due to hammering affect the piece of iron?
Hammering hot iron to change its shape is called forging. Hammer blows force movement of iron crystals into different arrangements. If it's hot enough then the strain developed by hammering the iron crystals is relieved by recrystallization
Is magnetism a force?
Magnetism is a non contact force. So it is basically a force

How could you use density to tell the difference between a piece of iron and a piece of lead?
lead is more dense
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 temporary magnet?
a temporary magnet is a piece of soft iron that is magnetized while in the presence of a magnetizing field but demagnetizes the moment the iron is taken away from the magnetizing force
