Any conductor like copper or silver or aluminum
Connecting the electricity will activate the electromagnet.
Batteries range in output voltage from 1.2 volts for an AA rechargeable, to 12 volts for a car battery. There may be other voltages, for special purpose applications. Batteries supply DC (direct current), meaning that the current will only flow in one direction.What is considered "mains" electricity (from a plug or receptacle in the wall) is alternating current (the current is oscillating between flowing one direction, then the opposite direction then back and repeats). It oscillates at 50 or 60 times per second, depending on what country you live in. Also the voltage is between 100 volts and 250 volts, depending on the country, as well. These features enable the voltage to be changed up or down rather easily with transformer, and allow the electricity to be transmitted over long distances.But the alternating current and higher voltages also make your mains electricity much more dangerous to touch than a battery. A person's skin has pretty good resistance to electric flow, especially direct current. But with alternating current, if you touch a wire, charges can actually form under the skin and start flowing through your body, because your skin acts as a capacitor. Then, the oscillating current back and forth through your organs is much more damaging, possibly causing your heart to stop pumping.
Current electricity- is powered by things like power plants, wind mills, solar energy, and burning fossil fuels. Current electricity is used to power things like light bulbs, televisions, and kitchen products. Static Electricity- is powered by electrons moving from one thing to another and there is not enough power to power things we use everyday.
A material can be porous but also impermeable due to its surface structure. The molecular level can allow molecules of air to pass through, but not water molecules.many materials, such as GoreTex, has a surface structure, that at a molecular level can allow molecules of air to pass thru but not molecules of water. This way, you can be protected from falling rain, but also have a material that will "breathe" and wont keep you feeling muggy inside.
When sodium oxide Na2O is added to water it is converted into sodium hydroxide immediately Na2O + H2O = 2NaOH , the ions Na+ and OH- in aqueous solution are responsible to conduct the electricity.

A conductor - usually copper wire.
Yes, copper wire is a conductive element and is the most addiquite substance for distribution of electricity known.

If you mean "dis"allow the flow, it's because electrons cannot travel easily between the atoms of the material.
I guess you mean, between a battery and something else.The generic name for materials which allow an electric current to flow through is "conductor". Specific examples include any metal, graphite, ions in a water solution.
A material that does not conduct (or allow the 'passage' of) electricity is called an "insulator".
