Depends on what the rooms are used for and how far the service panel is from those rooms. Bedrooms, living rooms, dens, and dining rooms take far less wire than a kitchen. Without knowing the details it is impossible to say. I will guarantee you will need at least 2,000 feet of 12/2. Beyond that hard to say.
Do you mean what is its value? How thick is the wire?
Most electrical coils and solenoids, use copper wire.
If you have some coils of wire and a house that needs rewiring, an electrician is needed to complete the job. He/she would also know if the wire you have is the correct wire to use in the rewiring.
If you wire all 4 coils parallel, you get 1 ohm (mono).
Increasing the coils will increase the strength of the magnetic field.
Coils of wire and a magnet. When magnetic lines of force move across a wire, it causes electrons in the wire to move. Those moving electrons are electrical current. In a generator, either the magnet or the coils of wire spin.
Some DC motors.
I would expect a voltage in both coils of wire.Note that, if the two coils are connected, the voltages (and corresponding currents) in the coils can interact. Also, if the two coils are NOT connected, they can STILL interact, since a current will produce its own magnetic field.
The coils are bolted to the ignition control module, there is no coil wire as such.
Any time an electric current passes through a wire, this will produce a magnetic field. If you want to make the field stronger, loop the wire into coils. The more coils you make, the stronger the field will be.
Coils of wire
The windings of magnet wire are made on a machine that counts the loops of wire as they are formed into usable coils. Once the coils are complete they are installed into the stator slots in a specific order.
