What else can I help you with?
A north pole will attract a piece of unmagnetised steel?
Only by inducing a magnetic field within the "unmagnetised steel".
Why heat demagnetised the steel?
A piece of metal can be magnetized if the atoms of which it is composed are magnetic, and they have aligned their north-south poles to point in the same direction. Heat increases atomic vibration and will cause these atoms to lose their alignment and point in all different directions, so that their atomic magnetic fields will not combine to form one large magnetic field.
Will steel stick to a magnet?
yes, generally stainless steel is magnetic
What is the melting point of high carbon steel?
The melting point of high carbon steel is typically around 2,500 to 2,800 degrees Fahrenheit.
How is a permanent magnetic created and what are the key steps involved in the process?
A permanent magnet is created by aligning the magnetic domains within a material, such as iron or steel, in a specific direction. This alignment is achieved through a process called magnetization, which involves exposing the material to a strong magnetic field and then cooling it to lock in the alignment of the domains. The key steps involved in creating a permanent magnet include selecting the appropriate material, magnetizing the material, and then shaping and finishing the magnet to meet the desired specifications.
What is the difference about the domains in a magnetised steel bar and one that is unmagnetised?
The difference is the domains are facing in random directions in the unmagnatised and in the magnatised they are all facing the same way!
What is the diffrent between a magnetised steel nail and an unmagnetised steel nail?
what is the diffrence between a magnetised nail and a unmagnetised nail
A north pole will attract a piece of unmagnetised steel?
Only by inducing a magnetic field within the "unmagnetised steel".
Will the north pole of a magnet attract a peice of unmagnetised steel?
That depends on the steel. If it is a ferrous steel the magnet (either North or South) will attract it - If it is a a stainless steel that is austenitic steel it will not.
Which is a to make a steel rod into a magnet?
To turn a steel rod into a magnet, you can use a process called magnetization. This can be done by rubbing the rod with a strong magnet in one direction, aligning the magnetic domains within the steel. Alternatively, you can place the steel rod in a strong magnetic field, such as that produced by an electromagnet, which will also align the magnetic domains and create a permanent magnet.
Curie point of carbon steel?
The Curie point of carbon steel is around 770°C (1,418°F). This is the temperature at which the material loses its magnetic properties due to the alignment of its magnetic domains changing. Beyond this temperature, carbon steel becomes non-magnetic.
What can happen when you rub a magnet on a paper clip?
A paper clip is made up of iron or steel. It consists of particles called domains which are randomly arranged. When a magnet is rubbed on a paper clip, the domains arrange themselves in one direction. Thus it gets magnetized and behaves as a magnet.
Why heat demagnetised the steel?
A piece of metal can be magnetized if the atoms of which it is composed are magnetic, and they have aligned their north-south poles to point in the same direction. Heat increases atomic vibration and will cause these atoms to lose their alignment and point in all different directions, so that their atomic magnetic fields will not combine to form one large magnetic field.
Will a magnet attract steel paper clip?
Yes, this is true because in magnet, there are many small domains which all point the same way... this makes a magnet wot it is. the reason that a papa clip will attract to a magnet is because of all the domains (tiny magnets) inside swerve around when they feel the pulse of the magnets field.. by hazap ........... .......... brap brap!
Why is magnet unable to stick to a stainless steel refrigerator?
If a magnet doesn't stick to a material, that means that the material is non-magnetic. Every individual atom is a magnet, but in a magnetic material, there are groups of atoms (called "magnetic domains") that have their magnetic directions aligned. An outside magnetic field in such materials will align some of the magnetic domains in the direction of the magnetic field.
Why steel becomes a permanent magnet after electric current is passed through it?
When an electric current passes through steel, it creates a magnetic field within the steel. This magnetic field aligns the magnetic domains in the steel, causing it to become a permanent magnet. The alignment of the magnetic domains allows the steel to retain its magnetism even after the electric current is removed.
Is magnetizing steel a chemical or a physical?
physical, just the aligning of magnetic domains what were previously random in orientation.
