The elements Fe, Ni, and Co and many of their alloys are typical ferromagnetic materials. Ferromagnetic materials exhibit parallel alignment of moments resulting in large net magnetisation even in the absence of a magnetic field.

What can be magnetised?
ferro magnetic substances can be magnetised. but it is not necessary that all the Ferro magnetic substances can be permanently magnetised. it depends on the alignment of domains in the substance.for example wrought iron can be magnetised permanently but soft iron can only be magnetised temporarily(Electro Magnets).
Are ferro magnetic materials insulators?
Not necessarily. Ferromagnetic materials can be conductors, semiconductors, or insulators depending on their specific composition and structure. Magnetic properties and electrical conductivity are independent characteristics of a material.
What is hysteresis effect?
In simplest terms, hysteretic damping is the energy lost in materials due to friction between molecules, and is related to displacements during vibration. It is also known as 'material damping.'
Are materials with magnetic properties magnetic materials?
Yes, materials with magnetic properties are often referred to as magnetic materials because they exhibit characteristics such as attracting or repelling other materials with magnetic properties and the ability to create magnetic fields.
What are non magnetic materials called?
Non-magnetic materials are often referred to as diamagnetic materials. These materials have a weak or no response to magnetic fields and are typically repelled by magnets. Examples include wood, plastic, copper, and water.
What are ferro-magnets composed of?
Ferro-magnets are composed of materials that contain magnetic domains which align in the same direction, producing a strong magnetic field. Common materials used for ferro-magnets include iron, nickel, and cobalt. These materials have unpaired electrons that contribute to their magnetic properties.
What can be magnetised?
ferro magnetic substances can be magnetised. but it is not necessary that all the Ferro magnetic substances can be permanently magnetised. it depends on the alignment of domains in the substance.for example wrought iron can be magnetised permanently but soft iron can only be magnetised temporarily(Electro Magnets).
Why some materials are magnets and some are not magnet?
Ferro magnetic materials (those attracted to magnets) have a special arrangement of their electrons which makes them susceptible to magnetic fields. Materials without this special electron structure are not affected my magnets or electric fields in the same way.
Are ferro magnetic materials insulators?
Not necessarily. Ferromagnetic materials can be conductors, semiconductors, or insulators depending on their specific composition and structure. Magnetic properties and electrical conductivity are independent characteristics of a material.
What happen to the magnetic flux when it passes through a ferro-magnetic substance?
When magnetic flux passes through a ferromagnetic substance, the substance can become significantly magnetized. This is due to alignment of magnetic domains within the material, enhancing the overall magnetic effect. Ferromagnetic materials have a high magnetic permeability compared to non-magnetic materials, allowing them to concentrate magnetic lines of force.
Name a magnetic material?
exmaples of magnetic materials are iron,nickel,cobalt,paper clips,nails and some pins....:-)Example (A Science Trick):COINS=CO-BALTI-RONN-ICKLES-TEEL
Is sand a non ferro magnetic or not?
Sand should not be ferromagnetic
Permanent magnets can lose their magnetic properties if they are heated Explain why magnetic properties are lost under these conditions?
When a permanent magnet is heated, the temperature disrupts the alignment of the magnetic domains within the material. This causes the magnetic field to weaken or even disappear altogether. The heat can increase the thermal energy in the material, leading to randomization of the domain orientations and loss of the magnetic properties.
What are three examples of good magnetic materials?
iron , cobalt and nickel are good magnetic materials. ------------------------------------------------------- Fe Co Ni. ie Ferrous, Cobalt and Nickel are the three ferro magnetic materials. It is better to say as rhyming with Marconi. FECONI. One more important secret is Ferrous is having 26 as its atomic number, Co 27 and Ni 28. All the three are neighbours being seated in the periodic table.
Why are some materials attracted to magnets and others not?
Ferro magnetic materials (those attracted to magnets) have a special arrangement of their electrons which makes them susceptible to magnetic fields. Materials without this special electron structure are not affected my magnets or electric fields in the same way.
What is hysteresis effect?
In simplest terms, hysteretic damping is the energy lost in materials due to friction between molecules, and is related to displacements during vibration. It is also known as 'material damping.'
What is the difference between magnetic materials and non-magnetic materials?
Magnetic materials are materials that can be magnetized and can create a magnetic field, such as iron and nickel. Non-magnetic materials do not respond to magnetic fields and cannot be magnetized, such as wood and plastic.
