What is the role of magnetism in the process of stellar birth?
There is no known role of magnetism in stellar evolution.
What is closely related to magnetism?
Electricity, magnetism and electricity are two aspects of a single force known as electromagnetism.
What materials shield magnetism and are electrically non-conductive?
basically magnetic fields can only be blocked or contained by conductive material such as the iron, electronic devices are shielded by metallic boxes to avoid interference. so, i don't think there's a known non conductive material that can block the magnetic field.
Does photons have magnetism?
Photons form elecromagnetic waves, it's well known that electomagnetic waves have both electric and magnetic components (there are connected H~[n, E]).Thus photones can "have" magnetism.
Is it known what really causes magnetism?
Magnetism is not caused, it is one of the four known forces: Strong nuclear force Weak nuclear force Electromagnetic force (magnetism) Gravitational force All matter has an electromagnetic force, the reason that we dont see objects stuck to each other, is that almost all matter on earth, has equal, positive, and negative polarity. Understanding how a charge becomes positive, and negative, is very complex, and involves quantum mechanics.
Does saltwater prove to retain heat the best or freshwater?
Answer: Pure water has the best capacity for heat of any material known to man, so any impurity must reduce its ability.
What is residualmagnetism?
The retained magnetic flux of the material, even after the removal of the external magnetizing force is known as residual magnetism.
The ability of a material that withstand scratches without breaking is known as?
Search it
What is the role of magnetism in the process of stellar birth?
There is no known role of magnetism in stellar evolution.
What is the study of the past magnetism in rocks known as?
This is known as paleomagnetism.
What type of magnetism is present in a bar magnet?
The known magnetism in a bar magnet is electromagnetism.
What is magnetism closely related to?
Electricity, magnetism and electricity are two aspects of a single force known as electromagnetism.
Is replusion a super test of magnetism?
Repulsion from a known pole of a magnet is the ONLY valid test for magnetism.
What is closely related to magnetism?
Electricity, magnetism and electricity are two aspects of a single force known as electromagnetism.
How do you isolate magnetism remaining in the core of a electromagnet after the coil current is removed?
Your question is confusing, as you do not explain what you mean by 'isolate'. If you mean 'allow the core to retain some magnetism', then this will always be the case when the current through the coil is reduced to zero. In order to remove this 'residual magnetism', you will need to reverse the direction of current through the coil. This is a feature of what is known as 'hysteresis', by which changes in the flux density of a core 'lags behind' changes to the magnetic field strength that creates it.
Who was William Gilbert?
William Gilbert was known for his discovery of magnetism.
When was copper first used as a material for bath tubs?
Copper was first used for bath tubs as a material in late 1910, the reason this was used as a material is because copper as an element is a great heat conductor and can also retain heat for a longer time that other well known materials.
