It depends on the size of the bar.
1.2kg/cm2
Iron is a ferromagnetic metal, and copper is not. Iron will be attracted to the magnet but the copper will not.
An electromagnet is made by wrapping many coils of copper wire round an iron bar. When electricity is send along the coiled wires, the iron bar becomes magnetised until the electricity is switched off.
what is iron rate per kilo
A solenoid consists of a coil with an iron core and a movable iron bar. The term was coined by French physicist, Andre-Marie Ampere.
iron bar first
both are same havier
Usually such magnets are made out of iron. If that is the case, I would expect its density to be similar to that of iron (approximately 7900 kg/m3).
1.2kg/cm2
1.000 kg (1000 grams/1 kg)(1000 mg/1 gram) = 1,000,000 mg/50 mg = 20,000 iron tablets produced
The density of Iron is a property of the Iron itself, and not related to how much you have of it.
A iron bar is a conductor

The iron bar would become more magnetic.
you have to mine iron ore then put it in a furnace and you will get an iron bar called an iron ingot.
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.
