Mainly iron, such as aluminum foil, cobalt, any iron coin, iron part of a pencil, specific iron rock called lodestone, and dull nail (the dull nail is actually shiny). Pretty much anything iron.
good conductors are better emitters
Metals are good conductors of electricity, two of the best conductors are silver and copper.
The rails are good conductors The wooden ties they rest on are insulators
Well, there are two poles to a magnet. A negative one and a positive one. Since metals are good conductors of charge and the paper clip is a metal object, they will attract. The charge of the paperclip is opposite the charge to one of the poles of the magnet.
No; an insulator by definition does not conduct electricity. We use these to protect ourselves from electricity, like the rubber in rubber gloves. Conductors, in contrast, are good...uh, conductors of electricity.
You should clarify what sort of energy you are talking about.
No, not all conductors will stick to a magnet. Only ferromagnetic materials, such as iron, nickel, and cobalt will be attracted to a magnet. Other conductors, like copper and aluminum, are not magnetically attracted because they are not ferromagnetic.
According to different conductors, magnet wires can be divided into copper-based magnet
That might depend on what material the magnet is made from, but usually magnets are made from metals or alloys, i.e., electrical conductors.
A magnet cannot use words to create an electric current. A moving magnet will induce electric current in adjacent conductors. This is usually described in terms of the rate that magnetic flux lines connecting the opposite poles of the magnet "cut" the conductors. The more flux lines cutting the conductors per second, the more current induced.

Generally speaking, materials that are good conductors of heat are good conductors of electricity. But there is a notable exception. Diamond, an allotrope of carbon, conducts heat better than any metal, but it is an electrical insulator.
metals
Metals, in general. Copper and silver are particularly good conductors.
A current of electricity flows through some conductors inside the motor. These conductors create a magnetic field which in turn moves the magnet connected to the rotor.
All metals are solids and good conductors apart from Mercury which is a liquid but is a good conductor.
