An electromagnet will lose most of its magnetism, once the current is turned off.
A temporary magnet is a magnet that only retains its magnetism for a limited period before losing its magnetic properties.
All entropy must increase to maxiumum. Ask Multivac.
Repeatedly hitting a magnet with a hammer may weaken its magnetic force by disrupting its alignment of magnetic domains. The impact could cause permanent changes in the magnet's structure, potentially reducing its overall magnetic strength. Over time, the magnet may lose its effectiveness and ability to attract or repel other objects.
The force of attraction between two magnets decreases with distance. At a distance of 6 inches, the closer magnet has a stronger force attracting the paper clip. At a distance of 12 inches, the farther magnet's weaker force is compensated by the extra time it has to act. Thus, the paper clips reach both magnets at the same time.
Yes, temperature can affect the strength of a magnet. Generally, magnets become weaker as temperature increases. This is because the increased temperature causes the atoms within the magnet to move more vigorously, disrupting the alignment of magnetic domains.
hold r3 with r1 at the same time
the domain strength is much stronger in a magnetised nail. when you have a weak nail, there is no magnetic force. sometimes they can repell. this is what i think and i always know best thank you
No, a signal that is band limited is not time-limited while a signal that is time-limited isnot band limited.
A temporary magnet is called a soft magnet. It can be easily magnetized and demagnetized, unlike a permanent magnet that retains its magnetism for a longer period of time.

A temporary magnet, such as an electromagnet, can attract iron but only for a short period of time. This type of magnet requires an external power source to create a magnetic field, which can be turned on and off as needed.
When a magnet is attached to a permanent magnet, it can become temporarily magnetized by aligning its magnetic domains with the strong magnetic field of the permanent magnet. This alignment causes the magnet to exhibit magnetic properties for a short period of time.
