What is the difference between ferromagnetic and paramagnetic materials in terms of their magnetic properties?
Ferromagnetic materials have strong and permanent magnetic properties, meaning they can be magnetized and retain their magnetism. Paramagnetic materials have weaker and temporary magnetic properties, meaning they can be magnetized but do not retain their magnetism once the external magnetic field is removed.
What else can I help you with?
Is ruthenium magnetic?
Yes, ruthenium is a ferromagnetic metal, meaning it is capable of being magnetized. However, its magnetism is generally considered to be weak compared to other ferromagnetic materials.
Why germanium is diamagnetic?
Germanium is diamagnetic because it has all of its electron spins paired, resulting in no net magnetic moment. This means that germanium does not exhibit magnetic properties in the presence of an external magnetic field, unlike paramagnetic or ferromagnetic materials.
What types of materials affect a magnetic field?
Materials that are ferromagnetic, such as iron, nickel, and cobalt, strongly affect magnetic fields. Other materials like paramagnetic and diamagnetic materials can also affect magnetic fields to a lesser extent. Factors such as the composition, structure, and magnetic properties of a material can influence how it interacts with magnetic fields.
What materials does the electromagnet repel?
An electromagnet can repel materials that are either ferromagnetic (such as iron or nickel) or paramagnetic (such as aluminum or copper) when it is energized. Non-magnetic materials like wood, plastic, or glass will not be affected by the repelling force of an electromagnet.
What are 4 common ferromagnetic materials found in nature?
Four common ferromagnetic materials found in nature are iron (Fe), nickel (Ni), cobalt (Co), and their alloys. These materials exhibit strong magnetic properties and are widely used in various applications such as in electromagnets and magnetic storage devices.
What is the curie point of water?
Water does not have a curie point because it is not a ferromagnetic material. Curie point is the temperature at which certain materials undergo a transformation in their magnetic properties from ferromagnetic to paramagnetic.
Is aluminium is ferromagnetic metal?
No. Iron (Fe = ferrous), is a totally different element.
What is the difference between dia- and paramagnetic materials in terms of their magnetic properties?
Diamagnetic materials are weakly repelled by magnetic fields, while paramagnetic materials are weakly attracted to magnetic fields.
Is chlorine attracted to magnet?
No. Chlorine is not a metal with magnetic properties.
What is meant by magnetic material?
Magnetic materials are substances that exhibit magnetic properties, meaning they can be magnetized or attracted to magnets. These materials can be classified into three main categories: ferromagnetic, paramagnetic, and diamagnetic, based on their response to magnetic fields. Ferromagnetic materials, like iron, can retain magnetization, while paramagnetic materials are weakly attracted to a magnetic field, and diamagnetic materials are weakly repelled. The behavior of these materials is due to the alignment of their atomic magnetic moments in response to external magnetic fields.
Does a ferromagnetic material lose its magnetic properties above certain tempetures?
Yes, ferromagnetic materials lose their magnetic properties above a specific temperature known as the Curie temperature. At this point, thermal energy disrupts the alignment of magnetic domains, causing the material to become paramagnetic, where it no longer retains its permanent magnetism. The Curie temperature varies for different materials, and once the temperature falls below this threshold, the material can regain its ferromagnetic properties.
Is ruthenium magnetic?
Yes, ruthenium is a ferromagnetic metal, meaning it is capable of being magnetized. However, its magnetism is generally considered to be weak compared to other ferromagnetic materials.
Why germanium is diamagnetic?
Germanium is diamagnetic because it has all of its electron spins paired, resulting in no net magnetic moment. This means that germanium does not exhibit magnetic properties in the presence of an external magnetic field, unlike paramagnetic or ferromagnetic materials.
What types of materials affect a magnetic field?
Materials that are ferromagnetic, such as iron, nickel, and cobalt, strongly affect magnetic fields.

Factors such as the composition, structure, and magnetic properties of a material can influence how it interacts with magnetic fields.
What happens above Curie temperature?
Above the Curie temperature, a ferromagnetic material loses its permanent magnetization and becomes paramagnetic. This occurs due to thermal energy disrupting the alignment of magnetic domains within the material, causing it to lose its magnetic properties.
Is silver ferromagnetic?
No, silver is not ferromagnetic. It is classified as a non-magnetic metal because it does not have strong magnetic properties like ferromagnetic materials such as iron, nickel, and cobalt.
Differentiative between diamagnetic paramagnetic and ferromagnetic?
Diamagnetic metals have a very weak and negative susceptibility to magnetic fields. Diamagnetic materials are slightly repelled by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Diamagnetic materials are solids with all paired electron resulting in no permanent net magnetic moment per atom. Diamagnetic properties arise from the realignment of the electron orbits under the influence of an external magnetic field. Most elements in the periodic table, including copper, silver, and gold, are diamagnetic. Paramagnetic metals have a small and positive susceptibility to magnetic fields. These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Paramagnetic properties are due to the presence of some unpaired electrons, and from the realignment of the electron orbits caused by the external magnetic field. Paramagnetic materials include magnesium, molybdenum, lithium, and tantalum. Ferromagnetic materials have a large and positive susceptibility to an external magnetic field. They exhibit a strong attraction to magnetic fields and are able to retain their magnetic properties after the external field has been removed. Ferromagnetic materials have some unpaired electrons so their atoms have a net magnetic moment. They get their strong magnetic properties due to the presence of magnetic domains. In these domains, large numbers of atom's moments (1012 to 1015) are aligned parallel so that the magnetic force within the domain is strong. When a ferromagnetic material is in the unmagnitized state, the domains are nearly randomly organized and the net magnetic field for the part as a whole is zero. When a magnetizing force is applied, the domains become aligned to produce a strong magnetic field within the part. Iron, nickel, and cobalt are examples of ferromagnetic materials. Components with these materials are commonly inspected using the magnetic particle method.
