What is the difference between hard and soft magnetic materials?

∙ 12y ago
Materials which retain their magnetism and are difficult to demagnetize are called hard magnetic materials.
These materials retain their magnetism even after the removal of the applied magnetic field. Hence these materials are used for making permanent magnets. In permanent magnets the movement of the domain wall is prevented. They are prepared by heating the magnetic materials to the required temperature and then quenching them. Impurities increase the strength of hard magnetic materials.
Soft magnetic materials are easy to magnetize and demagnetize.
These materials are used for making temporary magnets. The domain wall movement is easy. Hence they are easy to magnetize. By annealing the cold worked material, the dislocation density is reduced and the domain wall movement is made easier. Soft magnetic materials should not possess any void and its structure should be homogeneous so that the materials are not affected by impurities.

What is the difference between soft and hard magnets?
A soft magnet's magnetic field can be broken easily. A hard magnet's magnetic field can not be broken easily.

What is the difference between soft and hard objects explain?
Soft, are kinda squisht and hard thing well, there kinda hard...

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.
Difference between hard drive and magnetic tape?
A hard drive comes with the Computer. A hard drive is considered permanent as opposed to magnetic tape. The data in tape can be accessed only serially whereas randomly in hard drive.
What are the characteristic of hard materials?
After magnetization, they remain magnetic due to high levels of Br and Hc.
What is the difference between Bakelite and polythene in nature?
Made from different materials. Bakelite is hard and rather brittle, polythene is softer and flexible.
Do Hard magnetic materials make excellent permanent magnets?
Yes - in magentic terms, "hardness" = "permanence".
What is the similarity between a hard disk and a magnetic tape?
Both are magnetic media used to store information.
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.
The memory devices of computers such as hard disks and floppy disk drives use materials to store data?
magnetic
What is the relationship between the magnetic field and distance?
its a hard thing but iam smart
