How can you magnetise an iton needle permanently using a strong bar magnet?
You magnetize an iron needle permanently by stroking it with a strong bar magnet.
What metal is easier to magnetise iron or steel?
Iron.
Why a coil of wire with a direct current passing through it will magnetise a piece of iron?
The coil would act as if a bar magnet inserted along its axis. So any iron material inserted gets magnetised.
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 do you prove the object is magnetise?
hold a piece of iron or magnesium up to it and if it attracts it is magnetic
How will you use a solenoid to magnetise a steel bar?
When you pass an electric current through a solenoid, a roughly uniform magnetic field is produced inside the coils. Exposing a ferromagnetic material such as steel to a magnetic field will magnetise it, so placing a steel bar inside the coils of a solenoid with sufficient current passing through it will magnetise the bar.
Is a iron bar a insulator or a conductor?
A iron bar is a conductor
Is an iron bar a conductor or an insulator?
A iron bar is a conductor
Is an iron bar an insulator or a conductor?
A iron bar is a conductor
If an iron bar were inserted into the wire coil what would happen to the iron bar?
The iron bar would become more magnetic.
Does coil of wire with current passing through it magnetise a piece of iron?
yes it does the current flows in a wire it creates a magnetic field around the wire.
How do you make an iron bar on minecraft?
you have to mine iron ore then put it in a furnace and you will get an iron bar called an iron ingot.
