it prevents surrrounding magnetic field reaching the sensitive area of a piece of an equipment whose operation may be affected by the fields. magnetic shielding can address the problem of the damage of electronic equipment because of a great magnetic field like cell phones and computers
I assume you are referring to electron shielding.
Electron shielding is when electrons on the innermost levels of an atom "shield" the electrons that are likely to be found farther away from the nucleus. All electrons are attracted to the nucleus of an atom, where the protons are found. Those that are closer to the nucleus repel the ones farther away and prevent them from satisfying their crave for protons (metaphorical of course). Thus the term shielding is employed in chemistry.
Shielding- Reducing the ionization radiation reaching one region of space to the other by using a shield or other devise
the shielding effect is define as the decrease in attraction between an electron and the nucleus in any atom with more than one electron shell.It is also called screening effect.
The electron present in the inner shells screen or shield the force of attraction of electron felt by the valence shell electrons this is called sheilding effect.

What type of material will block alpha particles?
Materials like paper, clothing, or skin can block alpha particles. However, for stronger sources of alpha radiation, thicker materials like aluminum or plastic may be needed for effective shielding.
Does armour give shielding against EMI in cables?
Yes, armor on cables can provide some level of shielding against electromagnetic interference (EMI) by grounding any external electromagnetic interference that the cable may pick up. However, for more effective EMI shielding, additional specialized shielding materials like foil or braided shielding may be needed along with proper grounding techniques.
What are the other materials can be used as shielding in radiation?
Lead is the most commonly used metal as shielding in radiation. Lead is economical and has got very high atomic number. This very high atomic number makes it suitable as a shielding agent in radiation, probably. You can use other metals like steel also. Probably with less efficacy.
What materials deflect electromagnetic radiation?
Materials that can deflect electromagnetic radiation include metals like aluminum and copper, as well as specially designed materials with electromagnetic interference shielding properties such as conductive fabrics and metal-coated plastics. These materials work by reflecting or absorbing the radiation to prevent its passage.
Can magnetism be shielded?
Yes, magnetism can be shielded using materials that are poor conductors of magnetic fields, such as mu-metal or superconductors. These materials can redirect and absorb magnetic fields, reducing their influence on nearby objects.
What metal is good for magnetic shielding?
ferromagnetic materials
What is shielding in a nuclear reactor?
Shielding in a nuclear reactor refers to the materials used to contain and absorb radiation produced during nuclear reactions. These materials help protect workers and the environment from harmful radiation exposure. Common shielding materials include concrete, lead, and water.
What protective shielding is sufficient for gamma rays?
Materials with high atomic number, such as lead or concrete, are effective at shielding against gamma rays. The thickness of the shielding required will depend on the energy and intensity of the gamma rays. Multiple layers of shielding may be necessary to provide adequate protection.
Which type of radiation is most easily absorbed by shielding?
Alpha radiation is the most easily absorbed by shielding because it consists of large, heavy particles that interact strongly with other materials. Due to their large size and charge, alpha particles lose their energy quickly when they collide with shielding materials, making them easier to stop compared to other types of radiation.
What types of shielding material can be used to absorb gamma particles?
Lead, concrete, and steel are commonly used as shielding materials to absorb gamma particles. These materials are effective at reducing the penetration of gamma radiation and minimizing exposure to the surrounding environment. Specialized materials such as borated polyethylene and tungsten may also be used for more specific applications.
What is meant by diamagnetic shielding?
Diamagnetic shielding refers to the ability of a material to create a magnetic field in the opposite direction to an external magnetic field, thus reducing the overall magnetic field within the material. This shielding effect helps protect sensitive equipment or materials from the influence of external magnetic fields. Materials with diamagnetic properties include superconductors and some metals like bismuth and copper.
What type of material will block alpha particles?
Materials like paper, clothing, or skin can block alpha particles. However, for stronger sources of alpha radiation, thicker materials like aluminum or plastic may be needed for effective shielding.
Does armour give shielding against EMI in cables?
Yes, armor on cables can provide some level of shielding against electromagnetic interference (EMI) by grounding any external electromagnetic interference that the cable may pick up. However, for more effective EMI shielding, additional specialized shielding materials like foil or braided shielding may be needed along with proper grounding techniques.
What are the key materials in Primaloft?
The key materials in Primaloft insulation are ultra fine synthetic fibers which trap tiny pockets of air to create an effective layer of air shielding the wearer from the cold.
What are the other materials can be used as shielding in radiation?
Lead is the most commonly used metal as shielding in radiation. Lead is economical and has got very high atomic number. This very high atomic number makes it suitable as a shielding agent in radiation, probably. You can use other metals like steel also. Probably with less efficacy.
Is gold the best shielding against gamma radiation?
While gold is a common material used for shielding against gamma radiation due to its high density, it is not necessarily the best option. Lead is often considered a more effective and cost-efficient shielding material for gamma radiation due to its higher attenuation properties. Additionally, other materials such as tungsten and depleted uranium can also provide effective shielding against gamma radiation.
