Iron is a ferromagnetic metal, and copper is not. Iron will be attracted to the magnet but the copper will not.
It depends on the size of the bar.
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.
i would say that the 150 gram bar because the thermal energy will be able to travel around the bar quicker
The iron would react with the oxygen in the water to make iron oxide, or rust.
A iron bar is a conductor
A iron bar is a conductor
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.
an iron bar is harder to bend.
If you wrap a length of wire around the iron bar then pass a current through the wire, the bar will become magnetised.
Iron is a ferromagnetic metal, and copper is not. Iron will be attracted to the magnet but the copper will not.
true
This is incorrect. A bar of lead is denser than a bar of iron. Iron bars have a density of 7.87 g/cm3, whereas lead bars have a density of 11.36 g/cm3.
It depends on the size of the bar.
