What magnetic material is easy to magnetize but loses its magnetism easily?
Wiki User
∙ 12y ago
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 a non-magnetic material?
Non magnetic material is the one which cannot be easily magnetized even with intense magnetic field around it.
What do magnetically soft substances do?
magnetically soft substances gain there magnetism easily but also lose it easily
What is a material that could not be scratched easily?
A material that is not easily scratched is _____.
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 a material that doesn't allow charges to move through it easily?
Wood An insulator is a material that does not allow charges to move through it easily.
Distinguish between the magnetic properties of iron and steel?
The magnetic properties of iron are high susceptibility and low retentivity. It means that it is easier to magnetize but also loses magnetism easily. The properties of steel are the opposite of iron.
What role is played by molecular magnets to magnetize and demagnetize bodies?
The relative coercitivity of a material helps to magnetize and demagnetised a substance. If the coercitivity id low then the material can be easily demagnetized and vice versa. A substance can be magnetized by creating magnetic filed of opposite charges and demagnetized by creating same filed of charges.
What is a non-magnetic material?
Non magnetic material is the one which cannot be easily magnetized even with intense magnetic field around it.
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.)
Does glass magnetize easily?
No its not a metal.
Why do electromagnets often have iron cores in them?
The main advantage of an electromagnet is it can be turned on and off. Iron is a soft magnetic material an therefore looses its magnetism very quickly, if you use a metal like like steel it will not loose it magnetism very easily and even if you turn off the current it will remain a magnet.
What is the difference between a permanent magnet and a temporary magnet?
Temporary magnet: good example is an electromagnet. It maintains magnetic attraction only so long as an electric current surrounds it. Permanent magnet: most common. Example: bar magnet. Will maintain magnetic properties for quite a while, although they can be eventually demagnetized.
Why is a soft iron core used in a relay coil?
because it can magnetize and demagnetize easily
How would you describe magnetic domains?
Each magnetic domain has a magnetic field. When an external magnetic field is applied, the magnetic domains will partially align, so the magnetic fields reinforce one another - instead of canceling one another, which is what happens when they are randomly distributed.
What does ferromagnetic mean?
Definitions of ferromagnetic on the Web: * relating to or demonstrating ferromagnetismwordnet.princeton.edu/perl/webwn * Ferromagnetism is the "normal" form of magnetism, with which most people are familiar, as exhibited in horseshoe magnets and refrigerator magnets. It is responsible for most of the magnetic behavior encountered in everyday life. ...en.wikipedia.org/wiki/Ferromagnetic * of a material, such as iron or nickel, that is easily magnetizeden.wiktionary.org/wiki/ferromagnetic * ferromagnetism - phenomenon exhibited by materials like iron (nickel or cobalt) that become magnetized in a magnetic field and retain their magnetism when the field is removedwordnet.princeton.edu/perl/webwn
What kind of material can electricity pass through?
Material with low conductance such as rubber, plastics and so forth.
Why is soft iron used for the core of an electromagent?
The main advantage of an electromagnet is it can be turned on and off. Iron is a soft magnetic material an therefore looses its magnetism very quickly, if you use a metal like like steel it will not loose it magnetism very easily and even if you turn off the current it will remain a magnet.
