What factors would affect the strength of the temporary magnet?
It depends on how you magnetize the temporary magnet.Material: Hard steel are harder to magnetize but harder to demagnetize compared to soft iron, so depending on duration, hard steel might be better (the longer the duration the better hard steel will be)Strength of original magnet (by induced magnetism): Of course, the stronger the first magnet, the more magnetism will be transferred.Number of coils (by electromagnetism): The more the merrier of course, where more coils mean more current flowing through (or around) it.
Differences between the magnetic properties of steel and iron?
Iron 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. If the magnets used in these devices were to retain their magnetism for a longer period, the devices would not function properly. Steel is slow to be magnetized but retains the acquired magnetism for a long time. Steel is said to have low susceptibility but high retentivity. Steel is used for making magnets.
Is a floppy disk attracted to a magnet?
The 3.5 floppy disk does have magnetism within them and for this reason, magnets destroying data on the floppy disk fueled the myth about magnets destroying your computer. If you buy a cheap magnet and put it near a floppy disk, the magnet will stick to it. After a few seconds, the information on that floppy disk will be destroyed and you will no longer be able to access the data.
Does a battery last longer when it is surrounded by magnets?
No, batteries don't charge faster when around magnets. It charges at the same speed.
Do you have to be a natural to be a boxer?
No. You just have to train longer and harder is you are not
What to do when your girlfriends keeps seeing her ex secretly?
Confront her on it. The longer you put it off the harder it will be, and the longer she is doing that to you the harder it will be between you. Trust me, confrontation is the key in a situation like this.
Would a magnet to last longer in hot or cold weather?
It would last longer in cold weather because heating causes a magnet to lose its magnetism.
What are the advantages and disadvantages do electromagnets have?
There are many reasons why electromagnets shouldn't be used. For example, permanent magnets are better to use economically because there is no cost of operation, like an electromagnet. There is also no maintenance or hardly any setup required. For permanent magnets, they can be used for a lot longer than electromagnets becausecan be used in hazardous places and are they are unaffected by shock or vibrations. Electromagnets require electricity to run, which costs money. They also burnout or lose its magnetism after a while. There are also many reasons why electromagnets should be used. For an electromagnet, a person could easily control the power of the magnetism, unlike the permanent magnet which has the same intensity throughout. A person could also turn the power of the magnet on and off, which can become useful in certain situations. An electromagnet can also be made stronger than permanent magnets. The electromagnet also has a good field of depth, unlike the permanent magnets limited field depth.
