The price of an iron bar can vary significantly based on factors such as market demand, quality, and location. As of recent estimates, the cost typically ranges between $0.50 to $1.50 per pound. For bulk purchases, prices might be lower, while specialty or high-grade iron bars could be more expensive. It's best to check with local suppliers or online marketplaces for the most current pricing.
You can differentiate between a bar of iron and a bar of copper by testing their magnetic properties - iron is attracted to magnets, while copper is not. A bar magnet will attract small iron objects, while a bar of copper will not be attracted.
The weight of an iron bar can vary depending on its dimensions and density. However, a common estimate for a standard iron bar is around 7.85 kg per meter in length for a bar with a diameter of 25 mm.
A coil with an iron core and a movable iron bar constitutes an electromagnet. When an electric current flows through the coil, it generates a magnetic field that attracts the iron bar, causing it to move. This device is commonly used in various applications such as in electric motors and doorbells.
A short standard iron bar is a solid, straight metal rod typically made of iron or steel, with a standard length that is shorter than average for a standard iron bar. It is commonly used in construction, manufacturing, and other industrial applications for structural support or reinforcement.
The second iron bar with a mass of 300 grams has the most thermal energy because thermal energy is proportional to both mass and temperature. The greater mass of the second iron bar means it will have more thermal energy compared to the first iron bar with a mass of 150 grams, even if they are both at the same temperature of 250°C.

you have to mine iron ore then put it in a furnace and you will get an iron bar called an iron ingot.
You can differentiate between a bar of iron and a bar of copper by testing their magnetic properties - iron is attracted to magnets, while copper is not. A bar magnet will attract small iron objects, while a bar of copper will not be attracted.
an iron bar is harder to bend.
An iron bar is a conductor of electricity due to its ability to allow the flow of electrons. Iron has a high electrical conductivity compared to insulators like rubber or plastic.
If you wrap a length of wire around the iron bar then pass a current through the wire, the bar will become magnetised.
The iron bar would become magnetized when inserted into a wire coil carrying an electric current. This is because the electric current induces a magnetic field in the coil, which in turn magnetizes the iron bar.
A relay is made up of a coil with an iron core and a movable iron bar. The movable iron bar in a relay is called a switch.
The weight of an iron bar can vary depending on its dimensions and density. However, a common estimate for a standard iron bar is around 7.85 kg per meter in length for a bar with a diameter of 25 mm.
To calculate the weight of an iron bar, you need to know its length. Assuming a standard density of iron, the weight of a 12mm iron bar to be one metric ton would require a length of approximately 82.5 meters. This calculation is based on the volume of the iron bar and its density.
The copper has a higher thermal expansion coefficient than the iron. The copper wants to get longer relative to the iron so the bar bends away from the iron strip. For example if iron is on top and copper on the bottom the bar bows downward. This seems opposite to your question conclusion
