no they can not.
Permanent magnets do not lose their magnetic ability. Temporary magnets, however, gain magnetic properties when they are touched or moved by a permanent magnet. The properties of a temporary magnet dissipates over time after the permanent magnet is removed.
You may mean 'permanent' in which case it's a material which retains it's magnetic field, unlike a temporary magnet.
Temporary magnet: good example is an electromagnet. It maintains magnetic attraction only so long as an electric current surrounds it. Permanent magnet: most common. Example: bar magnet. Will maintain magnetic properties for quite a while, although they can be eventually demagnetized.
A temporary magnet is something that has been magnetized that won't stay a magnet for long, such as a paperclip that you have rubbed with a magnet. A Permanent magnet is usually a Lodestone that is found naturally or is manufactured by a company. Permanent magnets are always magnetic.
That's a "permanent" magnet.
permanent magnet .
Yes, you will create a temporary magnet. EX: if you put and nail next to an iron magnet, the nail will be temporarly magnetic.

A permanent magnet is a magnet which will keep its magnetism for a very long time and is difficult to change. No, As I think a permanent magnet means they have abilities to hold the magnetism when they are magnetized. Such as Alnico permanent magnets, but in fact, they can be demagnetized,such as high temperature, hit each other,pulse waves, out magnetic field influence...What's more, different permanent magnetic material, have different abilities on holding magnetism,they can be used in different environments. you can find some details from some manufacturers website, to learn some knowledges.
A permanent magnet is a magnet that has been manufactured to "permanently" hold its magnetic field. Ferromagnetic material of a desired shape is heated above its Curie point, exposed to a large electromagnetic field, and cooled slowly while being held in that field. This allows the magnetic domains in the material to align themselves with the field of the electromagnet. Further, when the material cools below its Curie point, the magnetic domains will remain in the position they are in when the electromagnet is shut off. The magnet is now a permanent magnet; the magnet "holds" the magnetic field "imprinted" on it.
An electromagnet only retains major magnetic properties when a current is being run through it.AnswerWhether a material makes a permanent or temporary magnet depends on the nature of the ferromagnetic material involved. For example a coil with a steel core will retain much of its magnetic flux density when the current is switched off, whereas a coil with an iron core will lose most of its magnetic flux density when the current is switched off.
