If a bar copper is brought near a magnet the copper bar will be?
I have just taken the test and the answer is.. b.) unaffected by the magnet The copper bar will become reactive if/when magnet is in motion. example; if strong magnet is slid swiftly along copper bar by hand, reaction will occur as a reactive force or drag and can be easily observed by anyone willing to test it themselves. This reaction is a form of Induction.
Is forming a bar of copper into a wire chemical or physical change?
Physical. It is simply changing the shape or configuration of solid copper to another shape. Chemical changes cannot be reversed.
What are the most effective copper cleaning solutions available on the market today?
The most effective copper cleaning solutions on the market today include products like Bar Keepers Friend, Wright's Copper Cream, and Weiman Copper Polish. These solutions are specifically formulated to remove tarnish and restore shine to copper surfaces.
Where in the home are you most likely to see a copper back splash design?
Kitchens and wet bar areas in a house are where a copper back splash design might be seen. Copper back splash designs around the range or stove hood are a part of remodel ideas. Counter and wall back splash in the entertainment or bar area offer a unique accent.
Why was copper discovered so much earlier than iron was?
Copper occurs naturally in a pure form, making it easier for ancient civilizations to discover and use. In contrast, iron needs to be extracted from ore through a more complex and energy-intensive process, which may have contributed to its later discovery.
If a bar of copper is brought near a magnet the copper bar will be what?
If a bar of copper is brought near a magnet and rubbed it will get magnetized and would behave like magnet. But this would be temporary and this property would wear after some days.
What would the value of pure copper bar be?
As of 23 February 2016, copper is worth $2.11/pound. The value of the bar depends on the weight.
How can you tell the difference between a bar of iron a bar of copper and a magnet?
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.
Would a bar of copper contract if you placed it in a refrigerator?
All metals will expand and contract to some degree depending on the temperature.
Does a bar of copper and a bar of magnet attract?
A bar of copper does not attract a magnet. Copper is a non-magnetic material, meaning it does not have magnetic properties and cannot be attracted to a magnet. In contrast, magnets attract ferromagnetic materials, such as iron, nickel, and cobalt, but not copper. Therefore, there will be no interaction between a bar of copper and a magnet.
What would happen to the mass of a candy bar if it was cut in half?
If a candy bar was cut in half the mass would decrease.
What is 0.6734343434 in a bar notation?
It would be 0.6734 with a bar over the 34.
How can you calculate the copper bus bar according to the amp?
To obtain the amp of the copper bus bar, multiply the width of the bus bar by the thickness of the bus bar to obtain the current carrying capacity of the bus bar.
Where can one purchase a cheap copper bar sink?
Copper bar sinks can be found for a low price at many home improvement or bar specialty stores. Lowe's, The Home Depot, and Copper Sinks Online all have an inexpensive selection of bar sinks.
What supplies would you need to make an electromagnet?
You need an iron bar, some copper wire and a battery.
Would there be any electromagnetism if you coiled bare copper wire onto a shiny iron bar?
Yes, there would be electromagnetism generated when an electric current flows through a coil of bare copper wire wrapped around a shiny iron bar. The iron bar would increase the strength of the magnetic field produced by acting as a magnetic core, enhancing the electromagnet's performance.
Why a bar of the brass is harder than a bar of copper?
Because brass is an alloy of copper & zinc - the zinc atoms change the geometry of the copper crystals - making it less flexible.
