With a magnet or by sprinkling iron fillings an cardboard if you use it to see the pattern of magnetic field.
Yes
magnets detect iron because of the magnetic feild in the magnet which atracts iron to stick to it.
Nickel, cobalt, and iron.
Anything magnetic and a metal object.
Gold is non-ferrous and therefore is not attracted by a magnet. There are other metal that are attracted by a magnet but gold is not one of them. You can tell what is a ferrous metal and what is a non ferrous one but you cannot identify gold.
You can detect the magnetic field by its pull on another magnet, including a compass needle.
If you roughly know where North is, tie the bar magnet to a piece of thin string so it balances horizontally and let it dangle. Once it stops spinning and waving about, one end should point North. Mark this end as with an N for north.
An object is considered a magnetic object if it is attracted to a magnet or if it has its own magnetic field that can interact with other magnetic fields. This can be tested by observing if the object is drawn toward a magnet, or by using a compass to detect any magnetic field it may produce.
One way to prove the presence of magnetic form of iron in soil is to use a magnet. If the soil is attracted to the magnet, it indicates the presence of magnetic iron compounds. Another method is to analyze the soil samples using techniques like magnetic susceptibility measurements or Mössbauer spectroscopy to detect magnetic minerals like magnetite or maghemite.
Volt Metre is the apparatus used to detect the electricity generated. Moving a magnet in or around coil of enamelled copper wire or vice versa will generate electricity. The electricity generated can be detected, by connecting the ends of wires of coil to a Volt Metre. The Voltage generated proportional to the speed of movement and strength of the magnet, and the number of turns of the coil.
A magnet. It is described as a Magnet.
a mineral magnet can stick to a magnet because a mineral magnet has to poles the north and the south poles
