magnetise
You put a magnet in it poo face! dur
Rub the needle across a magnetic surface...always in the same direction, don't go back and forth. This will magnetise the needle. Then float the needle in a dish of water. And presto you have your own compass
You need to rub the needle with a magnet or you can use coil around the needle and pass current to make it a electro magnet.
Yes, however the object must be a magnetiseable metal such as iron. To magnetise it you could use a permanent magnet and slide it along the metal pice in one direction several times. Than you pice of iron for example would be a permanent magnet. Another way of doing this is, if there is no permanent magnet available, is to use a SOLENOID. You could build yourself one: Check it out on the internet. This solenoid would make your pice of iron permanently magnetic with the use of ELECTRICITY. This shows that magnetism and electricity are closely related. GUD LUCK and I hope my answer helped you.
what is the normal hardness of en8 material
what is magnetic ppermeability of EN8
The hardness of EN8 is usually between 500 N/mm2 and 800 N/mm2.
Yes.
Yes.
NO because the EN8 = A B C D E F G God you should know that
The magnetic materials which can magnetise and de-magnetise easily are called "soft magnetic materials" example:-ferrites,iron-cobalt alloy. The magnetic materials which cannot magnetise and de-magnetise easily are called "hard magnetic materials" example:-aluminium(al),nickel-cobalt alloy.
Yes
magnetise
you really can't
En8 is low carbon steel and it can be toughned. En24 is medium carbon steel and it is generally called forged steel.
