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.

What is the only time that electromagnets magnetise?
Electromagnets are only magnetised while the electrical current is switched on.
What kinds of materials make good semiconductors?
Copper is a very widely used semiconductor. Copper wire is used in electromagnets and electric motors. In electromagnets, it is wound around a metal core with electricity flowing through it to magnetise the metal core. And the same basic principle applies to small electric motors, only, they are encased in a magnet so the opposite sides cause force it into a centrifugal motion.
How do you magnetise a needle?
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.
What are hard and soft magnetic materials?
Colour: black, opaque. Streak: black. Lustre: metallic or dull. Cleavage: none. Hardness: 5.5-6.5. Specific Gravity: 5.2. Its diagnostic feature is that it is highly magnetic.
