What Is the Difference Between a Permanent and Temporary ...

Full Answer. The main difference between hard and soft magnetic materials is their coercivity, or the threshold an external magnetic or electric field would have to exceed in order to demagnetize the material. Hard magnetic materials have a much higher coercivity than soft magnetic materials.

Magnetic Properties of Iron and Steel - A Leading UK ...

Magnetic Properties of Iron and Steel Chains of paper clips can be hung from a magnet. Each paper clip magnetises the one below it by induction and the unlike poles so formed attract.

What Is the Difference Between a Permanent Magnet and a ...

The difference between a permanent magnet and a temporary magnet is that once the magnetization stops, a permanent magnet's atomic domains will remain aligned and have a strong magnetic field, whereas a temporary magnet's domains will rearrange themselves in a non-aligned manner and have a weak magnetic field.

Difference Between Magnetic Field and Magnetic Flux

Oct 07, 2015 · Magnetic field and magnetic flux both refer to properties of magnets. The main difference between magnetic field and magnetic flux is that magnetic field is a region where magnetic poles and moving charges experience a force. Sometimes, the term magnetic field may be also used to refer to the quantity magnetic field strength.

Difference Between Paramagnetic and Diamagnetic ...

Nov 30, 2013 · Difference Between Paramagnetic and Diamagnetic. Therefore, transition and inner transition metals show stronger magnetic effects due to the localization of 'd' and 'f' electrons and also due to the presence of multiple unpaired electrons. Some commonly known paramagnetic elements include Magnesium, Molybdenum, Lithium, and Tantalum.

The main difference in magnetic properties of soft iron ...

I ron gets magnetized faster but loses its magnetism as soon as the inducing magnet is removed. Hence soft iron is said to have high susceptibility but low retentivity. This property of soft iron is very useful in making temporary electromagnets where we need strong but temporary magnets.

The direction of the magnetic field is also indicated by these lines. The closer the lines, the stronger the magnetic field and vice versa. When iron particles are placed over a magnet, the flux lines can be clearly seen. Magnetic fields also generate power in particles which come in contact with it.

Types of Magnetic Materials - Electronics Tutorials

All types of materials and substances posses some kind of magnetic properties which are listed further down in this article. But normally the word "magnetic materials" is used only for ferromagnetic materials ( description below), however, materials can be classified into following categories based on the magnetic properties shown by them: 1.

Diamagnetism - Wikipedia

Diamagnetism is a property of all materials, and always makes a weak contribution to the material's response to a magnetic field. However, other forms of magnetism (such as ferromagnetism or paramagnetism ) are so much stronger that when multiple different forms of magnetism are present in a material, the diamagnetic contribution is usually negligible.

Difference Between Steel and Aluminum | Difference Between

We can understand this difference between steel and aluminum by a comparison based upon strength and weight, stiffness and yielding, and magnetic and nonmagnetic properties. As we know, strength refers to the maximum load a material can bear without bending and loosing its shape, and the stiffness refers to the yielding properties of a material, and how much it can bend under a load or when pressure is .

Magnetic vs. electric properties of materials :: Condensed ...

The only difference is that the polarisation is measured in the same units as the displacement field, the equivalent of the B-field rather than the H-field. As is the case in magnetism, there are electric states of matter characterised by temporary, induced dipole moments ( dielectrics ) and ones involving permanent charge separations with resulting permanent dipole moments ( paraelectrics ).

An important finding is that our silica-hybrid magnetic materials exhibit larger values of coercivities than the carbon based supports, which may be due to the difference in the insulation properties of the supports. Coercivities values range from 500 Oe [CNC, carbon-based] to 3500 Oe [SBA-15, silica-based].
