False. A north pole will repel a piece of unmagnetised steel. Only if the piece of steel becomes magnetised will it then be attracted to the north pole.
In unmagnetized steel, the domains point in random directions. This results in a net magnetization of zero as the magnetic moments cancel each other out.
In a non-magnetized piece of iron, the domains are randomly oriented, canceling out any magnetic effect. When the iron is magnetized, the domains align in the direction of the applied magnetic field, resulting in a net magnetic effect. This alignment creates a magnetic field within the material, making it behave as a magnet.
"Struck" is the past tense of the verb "strike," which can mean to hit, collide with, or make contact with forcefully. It can also mean to be affected by a particular situation or emotion.
Mean square distance is a statistical measure that provides information about the dispersion of data points from the mean. It is commonly used in various fields such as physics, engineering, and finance to quantify the variability of a dataset. A smaller mean square distance indicates that data points are closer to the mean, while a larger mean square distance suggests more variability in the data.
what is the diffrence between a magnetised nail and a unmagnetised nail
False. A north pole will repel a piece of unmagnetised steel. Only if the piece of steel becomes magnetised will it then be attracted to the north pole.
The difference is the domains are facing in random directions in the unmagnatised and in the magnatised they are all facing the same way!
In unmagnetized steel, the domains point in random directions. This results in a net magnetization of zero as the magnetic moments cancel each other out.
That depends on the steel. If it is a ferrous steel the magnet (either North or South) will attract it - If it is a a stainless steel that is austenitic steel it will not.
Put it in a coil which has an alternating current in it. The AC current produces a magnetic field in the coil which alternates with the changing voltage. This changes the magnetism of the permanent magnet. Gradually reduce the current in the coil and the permanent magnet will end up unmagnetised.
In a magnetized material, the iron atoms align their magnetic fields in the same direction, creating a net magnetic field. This allows the material to attract or repel other magnets. In an unmagnetized material, the iron atoms have random magnetic orientations, resulting in no net magnetic field.
