Quick Answer: Which Of The Following Is An Example Of Soft Magnetic Material?

What are hard and soft magnetic materials give one example of each?

The best examples of soft magnet are iron-silicon alloys, nickel-iron alloy and iron.

Hard magnetic materials: These Magnetic materials retain their magnetism in absence of magnetic field and also known as permanent magnets.

Alloys composed of iron, cobalt and aluminium are generally acted as hard magnetic materials..

What is soft and hard magnetic material?

1. Soft magnetic materials are those materials which have a smaller area enclosed by their Hysteresis loop. Hard magnetic materials are those materials which have a Larger area enclosed by their Hysteresis loop.

What are soft and hard materials give example?

Those materials which cannot be easily compressed cut ,moulded or scratched are called hard materials. For ex: Iron ,steel ,wood, stone ,brick, glass ,bone ,teeth, diamond. Those materials which can be easily compressed cut, moulded or scratched are called soft material.

What is an example of a soft magnetic material?

Common soft magnetic materials are iron, iron-silicon alloys, and nickel-iron alloys. Irons are widely used for their magnetic properties because of their relatively low cost. … There are about six types of nickel-irons, sometimes called permeability alloys, used in magnetic applications.

What are the examples of soft materials?

Answer. Examples include colloids, polymers, liquid crystals, gels, emulsions, foams and the tissue that makes up most of the animal world.

What are the characteristics of soft ferromagnetic materials?

Properties of Soft Magnetic MaterialsUtmost permeability.Slight coercive force.Small hysteresis loss.Small remanent induction.High saturation magnetisation.

Where are hard magnetic materials used?

Applications of Hard Magnetic MaterialsAutomotive: motor drives for fans, wipers, injection pumps; starter motors; Control for seats, windows etc.Telecommunication: Microphones, Loud Speakers, Telephone Ringers etc.Data processing: Printers, Stepping Motors, Disc Drives and Actuators.More items…•

What are hard magnetic materials?

Hard magnets, also referred to as permanent magnets, are magnetic materials that retain their magnetism after being magnetised. Practically, this means materials that have an intrinsic coercivity of greater than ~10kAm-1.

What are soft materials?

Soft materials are materials that can be easily deformed by thermal stresses or thermal fluctuations at about room temperature. Soft materials include liquids, polymers, foams, gels, colloids, granular materials, as well as most soft biological materials.

Is steel a hard magnetic material?

Magnetically hard materials can be permanently magnetized by a strong magnetic field. … Steel and special alloys, which contain various amounts of aluminum, nickel, cobalt, and copper, are used to make permanent magnets.

What is the magnetic material?

Definition. Magnetic materials are materials studied and used mainly for their magnetic properties. The magnetic response of a materials is largely determined by the magnetic dipole moment associated with the intrinsic angular momentum, or spin, of its electrons.

What is a magnetically soft material?

Substances that can only be temporarily magnetised are described as magnetically soft. Alloys with less iron, nickel or cobalt will be magnetically soft and have a weaker magnetic field.

Which is non magnetic material?

The materials which are not attracted towards a magnet are non-magnetic materials. Examples of non-magnetic materials include rubber, coins, feather and leather.

Why are soft magnetic materials used in electromagnets?

1 Answer. This is because soft iron has the property of losing its magnetism(or is able to be demagnetized) very quickly. An electromagnet works in this way: when current flows through it, it becomes magnetized, and immediately current stops flowing, it loses its magnetism.

What are soft magnetic materials used for?

Soft-magnetic materials are mainly used in magnetic cores of transformers, motors, inductors, and generators. Of prime importance for applications in cores are a high permeability, low magnetic losses, and a low coercivity.
