temporary magnets
What types of magnets are easy to magnetize but lose magnetism quickly?
Temporary magnets, such as soft iron and steel, are easy to magnetize but lose magnetism quickly because they have low coercivity. These types of magnets can be easily demagnetized by external factors such as heat or mechanical shock.
What magnetic material is easy to magnetize but loses its magnetism easily?
Soft iron is a good example of a material that can be strongly magnetized by an external magnetic field, but which loses most (or nearly all) of its magnetism as soon as the external field is removed. Generally, materials classed as Paramagnetic exhibit this behaviour. Many Ferromagnetic materials are designed to behave this way, such as the Ferrite cores of tuning coils in radio receivers.
What is the difference between hard and soft magnetic materials?
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.

Why is iron easy to magnetize when used in an electromagnet?
Iron has strong magnetic properties due to its atomic structure, especially its ability to align its magnetic domains easily. This makes it easy for iron to become magnetized when placed in a magnetic field, making it a common choice for use in electromagnets.
What type of magnets are easy to magnetize but Loose made quickly?
electronic magnets as they work with electricity produced

What does it mean by steel is magnetically hard?
A magnetically hard substance is one which can be permanently magnetised using a strong magnetic force. Steel is one such substance. (A magnetically soft substance can only be magnetised temporarily.)
What is good metal conductor that can be magnetized?
An ordinary steel sewing needle is easy to magnetize.
Is animal magnetism easy?
yes it is if u hav the required skills for it =
Does plastic constrain a magnetic field?
Not really. Plastics are almost all hydrocarbons, and the magnetic field lines go right through plastics like the plastics were invisible. That's the short answer, but it contains the essentials.
