bar magnet :- cuboid shapecylindrical magnet :- cylinder shape
As I recall, Lodestone (magnetite) was found in a place named Magnesia, hence magnet.
One way to know a coin is not silver is to check it with a magnet. If the magnet sticks to the coin, it is not silver. If the magnet does not stick, it still might not be silver. You can test it, but to do that you need a test kit.
It doesn't matter on the orientation, it is the attraction of the magnet to pull the contact and complete the circuit that matters.
When you rub a magnet with metal, the metal object becomes temporarily magnetized. This happens because the atoms in the metal align with the magnetic field of the magnet. However, once the magnet is removed, the metal object loses its magnetism.
To make a metal magnet, you can create a temporary magnet by stroking a metal material (like iron) with a permanent magnet in the same direction. This aligns the magnetic domains in the metal. For a more permanent magnet, you can heat the metal to a specific temperature and then cool it in the presence of a magnetic field to enhance its magnetic properties.
A magnet is an object that attracts metal due to its magnetic field. When a metal object comes in close proximity to a magnet, it is pulled towards the magnet due to the attractive force between the magnetic poles.
The exact same way that a normal magnet attracts metal.
a magnet is a metal thingy that can pull a metal object towards it
Some metals are naturally paramagnetic, meaing that you can induce a magnet field on it but only with a very strong magnet. To actually magnetize the metal itself without a magnet, you would have to make an induced magnet by wrapping the metal around a copper wire and sending electricity through it. It all has to do with the arrangement of the electrons within the metal.
Metal?
yes
Metal?
You can use a magnet to test if something is metal. If the magnet sticks to the object, it is likely made of metal. Another way is to check for properties like conductivity or density, which can also indicate if something is metal.
Ferrous metal is any metal that contains iron.Iron is attracted the a magnet.So to test if metal is ferrous pass a magnet close to it, if the magnet reacts then you have ferrous metal.
a scrap yard magnet is an electro magnet used to pick up bits of metal. this is used because it can drop the metal because it can be turned on and off
