What is a current-carrying coil of wires with many loops?
solenoid
Why two wires carrying current do not attract each other yet there are magnetic field around both the wires?
because the poles aren't defined. You create an electomagnet by coiling wire, and putting a piece of metal through it. Just the wire straight will cause magnetic field lines around the wire and as current goes up and down lines will move causing induction in neighbouring wires but that the extent of affect between wires. Without poles there is no opposite attract situation. The pole will constantly want to be ahead of the wire and the current will be constantly pushing it away. The metal defines poles plus directs the field lines.
If two wires run parallel and the current passes through both wires in the same direction?
they attract if they go opposite directions they repel
When electric currents flow in the same direction through two wires the wires attract each other why?
magnetism
What are the conductors in a circuit?
The wires carrying the power.
What happens to two parallel wires carrying electric current in opposite directions?
repel each other
What is a current-carrying coil of wires with many loops?
solenoid
Why insulation is needed on current carrying conductors?
To prevent the wire from getting short circuited to ground or even to other wires.

Why two wires moving along same path parallel to each other there magnetic field attract each other?
In the case of wires the net charges in two wires are zero everywhere along the wires. That makes the net electrical forces between the wires very nearly zero. Yet the relativistic magnetic forces and fields will be of the same sort as in the case of two beams of charges of a single sign. This is true even in the frame of reference of what we think as the moving charges, that is, the electrons. In the frame of reference moving at the drift velocity of these current-carrying electrons, it is the protons or positively charged ions that are moving in the other direction. Consequently in any frame of reference for current-carrying wires in parallel, the net electrical force will be essentially zero, and there will be a net attractive magnetic forc
Why current carrying wires become hot?
Resistance. Need larger gage wire
Why dont phase and neutral exchange?
Phase wires are "hot" wires and are the current-carrying conductors. (These are the wires that will shock you if you touch them.). The neutral wire is basically there to carry the electricity back to the source. It is not normally considered current-carrying. If you switch these two wires, you might energize the metal of equipment, causing a dangerous shock hazard.
If two wires run parallel and the current passes through both wires in the same direction?
they attract if they go opposite directions they repel
Why is it that 2 parallel wires carrying currents in opposite directions repel each other?
two wires carrying currents in opposite direction repel each other because the magnetic field between the wires is strong than on the sides of the wires.wires will move towards the weaker magnetic field from stronger field
How many hot wires does a 1990 Honda prelude have?
There is a Positive (HOT) & Negative (Ground) battery cable. There are also lots of other HOT wires that are carrying current throughout the vehicle. What exactly are you referring too? hundereds of wires get a book at advance or napa for your car
When electric currents flow in the same direction through two wires the wires attract each other why?
magnetism
When a graphic is a depiction of something real?
The graphic in the related link depicts the fields around wires carrying current. The current is real and the fields are also.
