When rusting occurs, some of the outer metal converts to a crumbly iron oxide that doesn't have the same strength as the metal.
The deeper the rusting goes into the metal , the weaker the bar will become.

Why the rusting of an iron bar decrease the strength of the bar?
When rusting occurs, some of the outer metal converts to a crumbly iron oxide that doesn't have the same strength as the metal. The deeper the rusting goes into the metal , the weaker the bar will become.
Why does the rusting of iron make the iron thinner and thinner?
When rusting occurs, some of the outer metal converts to a crumbly iron oxide that doesn't have the same strength as the metal. The deeper the rusting goes into the metal , the weaker the bar will become.
What happens to the molecules when a steel bar is left outside and starts rusting?
The molecules of iron combine with molecules of oxygen to form molecules of iron oxide- or rust.
Why is a iron bar placed in a solenoid?
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.
What is keeper and its use in magnetism?
A keeper is a iron or a steel bar that is used to retain the strength of magnet.
Why is magnetism induced into an iron bar placed near a magnet?
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.
What happens to the strength of an electromagnetic field when you increase the current flowing through the coil of wire around an iron bar?
Increasing the current flowing through the coil of wire around an iron bar will increase the strength of the magnetic field produced by the electromagnet. This is because magnetic field strength is directly proportional to the current flowing through the coil.
How does a bar magnet interact with iron filings to demonstrate magnetic field lines?
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.
Why does rust decrease the strength of an iron bar?
The reason for this is because rust is weaker than iron and decreases strength. Iron rust flakes off and has holes in it that allow water and air to further corrode deeper layers of iron (like a pile of potato chips). Aluminium, stainless steel and other metals form a complete continuous layer and prevent further corrosion. It is not because of reduced surface area if anything the surface area is increased (especially with iron)AnswerI believe its because the overall surface area of the bar is decreased, hence the structural integrity of the bar is compromised. Strangely enough, when aluminum rusts the aluminum oxide on the surface of the metal increases resistance to further corrosion without reducing the surface area. love Tim xxx

How do you make an iron bar on minecraft?
you have to mine iron ore then put it in a furnace and you will get an iron bar called an iron ingot.
