A current passing through a wire creates a magnetic field around the wire, due to effects of special relativity (the electrons are moving FAST). Alternatively, a changing magnetic field (such as created by a moving magnet) induces electric current in a nearby wire. Faraday's Law describes this behavior.
Steel is magnetic as are most ferrous metals. Fe = iron. Non ferrous metals are not magnetic. Some examples; aluminum, brass, copper, nickel etc. Stainless steel is non-magnetic because of the nickel content.
No, a extension cord cable is not magnetic. It is neither attracted to nor can it be picked up by a magnet.
Yes. and if you coil the wire, the more powerful the force becomes with the same energy.
yes
no
The cable is about 4 feet but you could use an extension cord with it.
Materials would consist of extension cord cable, male and female cap ends. The tools would consist of a screwdriver that will fit the termination ends screw configuration and a pair of wire strippers or a knife to strip the extension cord wire.
Assuming that the extension cord is plugged into a normal household receptacle rated at 15 amps the cord will handle 15A x 120V = 1800 watts. If the cord is of any length, at that wattage, you will feel the cord start to get warm like a heating cable.
Yes, but with a heavier gauge wire <<>> If the cord on an electric heater needs to be lengthened as a perminant feature then the whole cord should be replaced with a new cord of the same type and wire size. What this prevents is aquiring bad splice connections at the point the connection is made. Bad splice connections will create hot spots in the cable. If the lengthening of the cord is just a temporary fix, just use an extension cord. The extension cord should be the same wire size as the heater cord. Keep the extension cord under 20 feet in length.

An extension cord is a long power cord that plugs into an outlet and receives with an outlet. A computer cord just uses one long cable to transfer power to the computer from the outlet.
pretty sure it is an av cable
the answer choices are .. extension cord, power adapter, data cable, or telephone cord
You can plug an extension cord into another extension cord. A extension cord is to help make doing something easier.
The cable is about 4 feet but you could use an extension cord with it.

The procedure in making an extension cord involves wiring an electrical plug on one end of an electrical cable and wiring a socket onto the other end. Some extension cords have a polarized plug and a ground terminal.

No, but it is a waste of money when you only need three of the four wires when making an extension cord. If you are constructing an extension cord make sure that the ends go to the right end of the cable. Match the wire end when looking at it, to the proper pin configuration of the plug. White to silver, black to brass and green to green terminal. Looking at the end of the cable, it should be matched the plug configurations. On the plug end the wire should match the cable. If it doesn't look at the other end of the cable. No wires should cross when connecting to the blades on the plug, If they do you have the wrong end of the cable.
