A magnetic field can be diverted by a separate piece of ferromagnetic material?
Yes
Is cobalt a hard or a soft magnetic material?
Cobalt is ferromagnetic, but considerably less so than iron. Alloys of cobalt such as aluminium, nickel, cobalt and iron, known as Alnico, and of samarium and cobalt (samarium-cobalt magnet) are commonly used to make high quality permanent magnets.
What is remanence?
The magnetization left behind in a ferromagnetic material (e.g. iron) after an external magnetic field is removed.
A piece of magnetic material that retains its magnetic properties after it is removed from a magnetic field?
That's a "permanent" magnet.
Does most material have magnetic properties?
No, all materials do not have magnetic property. But if an iron is rubbed with a natural magnet,gets the properties of magnet.
What is a material that shows strong magnetic effects?
ferromagnetic material
Type of magnetic material used for small motors?
ferromagnetic material
Can a magnetic field be separated by a piece of ferromagnetic material?
Yes
A magnetic field can be diverted by a separate piece of ferromagnetic material?
Yes
A ferromagnetic material is best defined as any material that?
Contains Iron (fe) and is therefore magnetic.
Which material are magnetic?
Ferromagnetic materials like iron, cobalt, nickel and steel are magnetic. Most other materials are not.
Is cobalt a hard or a soft magnetic material?
Cobalt is ferromagnetic, but considerably less so than iron. Alloys of cobalt such as aluminium, nickel, cobalt and iron, known as Alnico, and of samarium and cobalt (samarium-cobalt magnet) are commonly used to make high quality permanent magnets.
Can you magnetize a bit of metal that is not a magnetic type of metal?
Generally, no you can't. A ferromagnetic material has what are called magnetic domains within it. These domains are effectively "tiny magnets" and are randomly arranged when they are in non-magnetized ferromagnetic metals. We can align them and make the material magnetic with the right equipment. A bit of metal that is not ferromagnetic has to domains to realign, so it can't be magnetized.
What is the effect of putting a ferromagnetic material inside the coil of a solenoid?
It strengthens the magnetic field
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.
