When a magnet or iron piece is watched under a powerful microscope we will obseve that a magnet or iron is made up tiny tiny pieces which cannot be further divided realistically such small pieces are known as domains.
In a magnet all domains are in the same direction due to which it attracts iron.
While in a iron these domains are arranged randomly which nullify its magnetism.
When a magnet is brousht near an iron matrial all the domains get attracted to the magnet due to which domains in iron get arranged in a particular direction due to wich at that time they act as magnets but as soon as the magnet gets farther the domains again arrange them selves randomly due to which tey do not remain permanent magnets

Why soft iron is used for making a permanent magnet?
Soft iron is not used for making permanent magnets; instead, it is used as a temporary magnet due to its high magnetic permeability and ability to be easily magnetized/demagnetized. Permanent magnets are typically made from hard magnetic materials like neodymium or ferrite, which can retain their magnetism for a long time.
What are ferrous materials?
Ferrous materials are metals that contain iron, such as steel and cast iron. These materials are known for their magnetic properties and are commonly used in construction, machinery, and other industrial applications. Ferrous materials are vulnerable to rust and corrosion.
What is true of permanent magnets?
Permanent magnets retain their magnetism without the need for an external magnetic field. They are typically made of materials such as iron, cobalt, and nickel, and have north and south poles that attract or repel each other. Their strength and duration of magnetism depend on factors like material composition and manufacturing process.
What are the 4 magnetic materials?
the 4 magnetic materials are iron, steel, copper and nickel
What do magnets pick up?
Magnets are attracted to materials that contain iron, nickel, and cobalt. These materials are known as ferromagnetic materials. Magnets will pick up objects made of these materials due to their magnetic properties.
Are permanent magnets only attracted to other permanent magnets?
No, permanent magnets can also be attracted to ferromagnetic materials such as iron, cobalt, and nickel. This attraction is due to the alignment of magnetic domains within the materials, resulting in an attractive force between the permanent magnet and the ferromagnetic material.
What is true about permanent magnets?
Permanent magnets have their own magnetic field that does not require external electrical current to maintain. They can attract or repel other magnetic materials without losing their magnetic properties. Common materials used for permanent magnets include iron, nickel, and cobalt.
How are temporary and permanent alike?
they're both magnets . they can both stick to iron-made materials. They are different because temporary magnets only last a little and permanent magnets last a long time.
Which materials can magnets be made from?
Magnets can be made from materials such as iron, nickel, cobalt, and certain types of rare earth metals like neodymium. These materials have magnetic properties that allow them to create magnetic fields and attract or repel other magnets or magnetic materials.
What is the difference between a permanent and non permanent magnet?
Permanent magnets are bar magnets or horse shoe magnets which has magnetism at all times. But non permanent also known as temporary magnets are usually electromagnets which would have magnetism only when current flows through the coil that surrounds it.
What is the difference between permanent magnets and temporary magnets?
One is temporary, the other is more or less permanent.
How are temporary and permanent magnets are alike and different?
Temporary magnets and permanent magnets are alike in that they both produce a magnetic field and can attract materials containing iron. However, temporary magnets only exhibit magnetic properties when exposed to a magnetic field, while permanent magnets retain their magnetism without the need for an external magnetic field.
Permanent and temporary magnets?
A temporary magnet is something that has been magnetized that won't stay a magnet for long, such as a paperclip that you have rubbed with a magnet. A Permanent magnet is usually a Lodestone that is found naturally or is manufactured by a company. Permanent magnets are always magnetic.
How are temporary magnets different from permaanent magnets?
temporary magnet permanent magnetit stays for a little while it stays foreverit is made from iron it is made from steel
How are temporary and permanent magnets alike?
Both temporary and permanent magnets generate a magnetic field, attracting objects made of magnetic materials. They both have a north and south pole and can be used in a variety of applications such as motors, generators, and sensors.
Do magnets attract iron and what other materials do they attract?
Yes, magnets attract iron and other materials such as nickel and cobalt.
What two materials are permanent magnets?
Permanent magnets are typically made from materials such as neodymium iron boron (NdFeB) and samarium cobalt (SmCo). Neodymium magnets are known for their strong magnetic properties and are widely used in various applications, while samarium cobalt magnets offer high resistance to corrosion and can operate at higher temperatures. Both materials are essential in creating strong, durable magnets used in everything from motors to electronics.
