Topic: MAGNETIC & NON-MAGNETIC SUBSTANCES PRIMARY 4 An Image/Link below is provided (as is) to download presentation. ... The fact about non-magnetic substance is that it has no reaction at all when brought near to a magnet. It is because only magnetic substance is attracted to a magnet.
Hence net magnetic moment of the substance is zero. Some examples of ferromagnetic substances are iron, cobalt, nickel, gadolinium, dysprosium etc. Properties of ferromagnetic substances (1) When placed in a non-uniform magnetic field, it moves from weaker to stronger parts of the magnetic field.
All other metals, including gold, silver and aluminum, are typically considered non-magnetic, although there are some elements that may show a slight positive or negative attraction when placed in a magnetic field. The elements that show a slight attraction to a magnetic field are known as paramagnetic substances.
The substances which are not attracted by a magnet are called non-magnetic substances. For example, wood, paper, water, copper, glass, gold, silver, etc., are non-magnetic substances. Types of Magnets Magnets are classified into two types namely, natural magnets and artificial magnets.
Non-magnetic: Such substances have little reaction to magnetic fields. They may be composed of molecules where electrons spinning one way are always balanced by electrons spinning the other, or their spins may simply interact only weakly.
Dec 17, 2011· Magnetic materials are things like iron, nickel, cobalt and their alloys. And there are other compounds that are magnetic, such as ferrites, alnico, and rare-earth magnets. Everything else is non-magnetic. A magnetized material is one of the magnetic material that is make into a magnet by various means, such as applying a brief external field.
Andy classified some substances as shown in the table. Andy's Table -Magnetic- -Non-magnetic- Steel Plastic Cobalt Paper Leather Wood Why is Andy's table incorrect? A)Wood is a magnetic substance. B)Paper is a magnetic substance. C)Cobalt is a non-magnetic substance. D) Leather is a non-magnetic substance.

For the purpose of electrical engineering it will suffice to classify the materials as simply ferromagnetic and and non-ferromagnetic materials. The latter includes material of ...
Nonmagnetic Materials paramagnetic, diamagnetic, and weakly ferromagnetic materials with magnetic permeability μ≦ 1.5. Nonmagnetic materials include most metals and alloys, polymers, wood, and glass. Metallic nonmagnetic materials—mainly nonmagnetic steels and cast irons, but also alloys of copper and aluminum—are most commonly used because of ...
Diamagnetic, Paramagnetic, and Ferromagnetic Materials When a material is placed within a magnetic field, the magnetic forces of the material's electrons will be affected. This effect is known as Faraday's Law of Magnetic Induction.
Magnetism is a force that can pass through non-magnetic materials, like paper. The thinner they are, the greater the magnetic force, so the ladybird will be moved easily by the magnet on the paper. It will often work through a table, but the magnet will need to be quite strong.
'The system, which is made of non-magnetic materials, has a range of 350m.' 'The tubing has to be a good conductor of electricity, and non-magnetic.' 'Other nano-scale structures under investigation include, for instance, non-magnetic carbon nanotubes.' 'The ships are constructed of non-magnetic …
In most substances, half of the electrons spin in one direction (clockwise) and the other half spin in the other direction (counterclockwise). However in some substances like iron, nickel, and cobalt, the electrons naturally spin more in one direction than another. ... Review with students what is considered "magnetic" and "non-magnetic."
What Metals Are Magnetic? Home Science Physics Magnetism. What Metals Are Magnetic? ... are man-made, and some are naturally occurring. For example, the mineral lodestone is magnetic. One of the first magnetic substances discovered, lodestone was used to create early compasses. ... list of non magnetic metals magnetic properties of metals table
Substances that are neither attracted nor repelled by a magnet are called non-magnetic substances. Examples are wood, glass and paper. Note: So, the student learns six years instead of the traditional five, but the university also visits much less often, namely during the installation session and during the examination period.
Materials that are not permanent magnets usually satisfy the relation M = χH in SI, where χ is the (dimensionless) magnetic susceptibility. Most non-magnetic materials have a relatively small χ (on the order of a millionth), but soft magnets can have χ on the order of hundreds or thousands.
2.8 Magnetic and non-magnetic materials (ESAAJ). We have now looked at a number of ways in which matter can be grouped, such as into metals, semi-metals and non-metals; electrical conductors and insulators, and thermal conductors and insulators.
We've addressed parts of this question before:, . Lots of other materials are magnetic, and many iron compounds aren't. Some simple elemental metals- e.g. cobalt, nickel, and neodynium-do have magnetic domains at room temperature, but most don't.
Ferromagnetic materials become magnetized when the magnetic domains within the material are aligned. This can be done by placing the material in a strong external magnetic field or by passing electrical current through the material. Some or all of the domains can become aligned.
The materials which get attracted towards a magnet are magnetic – for example, iron, nickel or cobalt. The materials which are not attracted towards a magnet are non-magnetic materials. Examples of non-magnetic materials include rubber, coins, feather and leather.

Substances such as copper, brass, wood, and glass are not attracted by a magnet, and are commonly described as non-magnetic. Nevertheless, experiments with very powerful magnets have shown that even the so called non-magnetic substances have very feeble magnetic properties.
