How could you magnetise a needle to make your own compass?
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
How can you magnetise a needle?
There are several ways. 1. Stroke the needle in one direction, with another magnet. 2. Place it in a coil of wire and pass a large (DC) current through the coil for a few seconds. (This is how they would do it commercially) 3. Align the needle with the magnetic north/south direction, now hit it several times. It will eventually take on the earths magnetic field as it's own.
What is the verb form for magnet?

What are hard and soft materials?
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.
How can you magnetise an iton needle permanently using a strong bar magnet?
Rub the iron needle along one direction on the strong bar magnet repeatedly until it becomes magnetized. Make sure to always rub it in the same direction to ensure a consistent magnetic field. This process aligns the magnetic domains within the iron needle, causing it to become permanently magnetized.
What metal is easier to magnetise iron or steel?
Iron.

What is the only time that electromagnets magnetise?
Electromagnets are only magnetised while the electrical current is switched on.
How do you prove the object is magnetise?
hold a piece of iron or magnesium up to it and if it attracts it is magnetic
What is the difference between a hypertonic needle and a hypotonic needle?
A hypotonic needle is a needle that is a non coring needle. A hypertonic needle is a coring needle. Both of these needles are used in IV's with a hypotonic needle used for hypotonic solutions.
What is a teasing needle?
