What happens when an electric current is passed through a conducting wire?
As the current flows along the lengths of the wire, charges also flow along its length. Therefore, when an electric current is passed through a conducting wire along its length, the electric field exists inside the wire but parallel to it. So, the correct answer is option B i.e. inside the wire but parallel to it.
Why would the wire attract iron filings when the current is on?
It takes a magnetic field that changes over distance to produce a net force that will attract and hold iron filings.
What happens when electric current passes through the electric iron?
When an electric current is passed through a conductor, the conductor becomes hot after some time and produce heat. This effect of electric current is called the heating effect of current. Example, Electric iron, electric toaster, water heaters, etc., work on this effect.
When electric current passes through a conducting solution it causes?
The passage of an electric current through a conducting solution causes chemical reactions. As a result, bubbles of a gas may be formed on the electrodes. Deposits of metal may be seen on electrodes. Changes of colour of solutions may occur.
Does iron have any effect on the filings?
A: Iron is one of the ferromagnetic elements. Each iron filing consists of numerous magnetic domains. It turns out these domains can lower their energy by lining up with their fields along the skinny direction of the filing.
What happened to the iron filings magnetism?
When the iron filings are sprinkled, those very close to the magnet, where the magnetic force is the strongest, will cling to the magnet. Those filings a little farther away, where the magnetic force is less strong, will align themselves with the magnetic flux lines, but they will not be drawn to cling to the magnet.
When electric current flows through a conductor the conductor becomes?
When an electric current flows through a conductor, it becomes hot because,the resistance of the conductor blocks the electricity flow by making collision of free electrons with the atoms and impurities. This collision produces heat energy.
Why does the iron filings attract the magnet?
Magnets attract iron due to the influence of their magnetic field upon the iron. When exposed to the magnetic field, the atoms begin to align their electrons with the flow of the magnetic field, which makes the iron magnetized as well. This, in turn, creates an attraction between the two magnetized objects.
How do you attract iron fillings on an insulated wire?
Any current flowing through a wire has magnetic fields given by the right hand thumb rule but to attract iron fillings you need a strong magnetic field which can be obtained by rolling the insulated wire over an iron nail..with this the ends of the nail will attract iron fillings once the ends of the wire are connected to a battery.
Does current pass through iron?
Yes, Current does passes through Iron. To understand this, see the picture below which shows metallic bonding.
How do ferrite filings become magnetic?
Iron filings are “ferri”-magnetic (ferrimagnetism) and essentially align themselves with the magnetic field being produced by a current in a conducting wire and under certain conditions become magnetic themselves (“ferro”-magnetic).
What is the relationship between electromagnetism and electric current?
When these two concepts are brought together they form the basis for electromagnetism. A moving electric charge can generate a magnetic field while with the help of a magnetic field, electric current can be induced into a conductor.
