Experiment I
Let a piece of glass and a piece of resin, neither of which exhibiting any electrical properties, be rubbed together and left with the rubbed surfaces in contact. They will still exhibit no electrical properties. Let them be separated. They will now attract each other.
If a second piece of glass be rubbed with a second piece of resin, and if the piece be then separated and suspended in the neighbourhood of the former pieces of glass and resin, it may be observed:

Stack two common flashlight dry cell batteries and tape them together at the middle, plus to minus, as you would normally load them into a flashlight.
Now take a length of small single stranded insulated copper door bell wire about the same diameter as a paper clip wire and about two feet long, and strip and each end about 1/2 inch.
Find a small screw driver and begin winding the wire around the shaft fairly tightly and uniformly from the handle down the shaft until just the tip of the blade is showing.
Be sure to leave about six inches of "tail" at each end of the wire, one near the handle, the other near the blade.
Now tape one tail to the bottom of the battery stack and the other to the top.
You will find that the screw driver is now magnetic, and you will be able to pick up small metal objects such as paper clips by touching the tip of the screw driver electromagnet
to them.
This same device is used in a much grander way at scrap metal salvage yards where very large pieces of metal are moved by an electromagnetic ring that is attached to a crane. The disc it attached to a cable with and is dropped into a pile of metal. Then the disc is energized, the metal sticks to it, and the crane picks up the metal and swings around to a rail car or hopper. The disc is de-energized and the metal then falls to its target point. The principle is essentially the same as your battery, wire and screwdriver.
Alternative AnswerPlace a compass near the wire. When current flows, the resulting magnetic field will cause the compass needle to deflect.
Yes, a current carrying conductor behaves like a magnet.
A magnetic pole is where the magnetic effect is greatest.
if there is no magnetic induction there will be no electricity
Yes, by moving the conductors through the magnetic field.
Magnetism, an aspect of electromagnetism, one of the fundamental forces of nature. Objects such as a bar magnet can influence other magnetic materials, without physically connecting them, because magnetic objects produce a magnetic field. Magnetic fields are usually represented by magnetic flux lines. Magnetic fields influence magnetic materials and also influence charged particles that move through the magnetic field.
The magnetic effect of electric current is known as electromagnetic effect. It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected because of flow of electricity. This shows that electric current produces a magnetic effect.
Yes, a current carrying conductor behaves like a magnet.
Solar wind has a large effect on the earth.. It brings these clouds (cant remember name) down. which affects electricity very much. Due to the magnetic field of the clouds

Electricity is like magnetic attraction because like charges in electricity repel similar to the way like magnetic poles repel.
No device. Because of magnetic shield no magnets can produce any effect on the rotation of the disk in the electricity meter. You better consume less electricity there by your bill will be in your budget.

A magnetic pole is where the magnetic effect is greatest.
Death, injury, and electricutionIf we ignore the above, humourous(!), attempt at an answer, then the three effects of an electric current are (1) heating effect, (2) chemical effect, and (3) magnetic effect.Examples of the heating effect include electric heaters, kettles, stoves, etc. An examples of the chemical effect is electroplating. Examples of the magnetic effect includes relays, motors, etc.The SI unit of current, the ampere, is defined in terms of the force between two parallel conductors due to their magnetic fields (i.e. the magnetic effect).
Iron filings will demonstrate the lines of magnetic force around a magnet.
