Water can conduct current, but not as efficiently as a copper wire. There are some applications where a small current is used to sense the level of water through a conductor in an insulated container.
A good conductor has high electrical conductivity, allowing electric current to flow easily. A semiconductor has moderate electrical conductivity, which can be controlled using external factors like temperature or doping. An insulator has very low electrical conductivity, preventing the flow of electric current.
because battery supplies a direct current and to make a magnet with using the electrical method you need to supply direct current to the material {metal}which must be wounded with a coil {solenoid}.

No, a conductor cannot attract an insulator using electrical charge because insulators do not allow the flow of electrons, making them unable to interact with a conductor's electrical charge.
Water is a conductor of electricity, and carries the electrical current. That being said, there is always a risk for electrocution when attempting to extinguish an electrical fire using water.
When working with a current carrying conductor, it is important to follow safety measures such as wearing insulated gloves and shoes, avoiding contact with water, ensuring the conductor is de-energized before touching it, and using proper tools and equipment to prevent electrical shocks or burns.
The question should be, "How should electrical current measured?" Current is measured in Amperes using an Ammeter placed in series with the conductor of the current. This is impractical, so most ammeters have windings of wire that pick up the field generated around the conductor in question. This winding, or coil, is very carefully sized and the meter very carefully calibrated to yield correct readings of current without a direct connection.
Electrical current is measured using an ammeter.
Batteries produce energy using a chemical reaction with electrolytes
Plastic enclosures are a form of case, which is used to seal the electrical compartments found in plugs. The plastic enclosure is an electrical insulator, which prevents the flow of the electrical current from discharging. Since it is an insulator and not a conductor, this can ensure the safety of using a plug.
A changing magnetic field, in the conductor, can induce a voltage (and, under the correct conditions, that in turn will result in a current). In the case of a permanent magnet, either the magnet or the conductor has to move.
