they have magnetic properties that weaken with time.
Electromagnets are temporary magnets made of iron usually that are created by passing a current through a wire wrapped around the iron. There are also ways of making temporary magnets out of ordinary iron objects that can later be demagnetized. I am not wise in the ways of these latter type of temporary magnets.

Temporary magnets and permanent magnets are alike in that they both produce a magnetic field and can attract materials containing iron. However, temporary magnets only exhibit magnetic properties when exposed to a magnetic field, while permanent magnets retain their magnetism without the need for an external magnetic field.
they're both magnets . they can both stick to iron-made materials. They are different because temporary magnets only last a little and permanent magnets last a long time.
Yes, temporary magnets are commonly used in door chimes. They are used to trigger the mechanism that produces the chime sound when the door is opened or closed. Temporary magnets are ideal for this application because they can be easily activated and deactivated as needed.
Temporary magnets can be used in various applications such as electric motors, speakers, and magnetic therapy. They can also be used in magnetic compasses, refrigerator magnets, and as a teaching tool in science experiments. Temporary magnets can be easily magnetized and demagnetized, making them versatile for different purposes.
One is temporary, the other is more or less permanent.
Temporary magnets, such as soft iron and steel, are easy to magnetize but lose magnetism quickly because they have low coercivity. These types of magnets can be easily demagnetized by external factors such as heat or mechanical shock.
Ferro-magnets, permanent magnets, temporary magnets, and electromagnets. Ferro-magnets are magnets that are magnetic at a higher temperature than room temperature. do not quote me on that. permanent magnets are magnets that are always magnets, they are the kinds you use a lot. Temporary magnets are things that are magnetic in an extrenal magnetic field. Last but not least, electromagnets. Electromagnets are coils of wire around a cobalt, nickel, or iron. When ou run electricity through the wire, the core and wire become magnetic.
They are temporary, they can only attract for a few seconds, as permanent magnets can attract for as long it is needed.AnswerA permanent magnet is a material which retains its magnetism once any external magnetising force has been removed. For example, when the current passing though a coil wound around that material is switched off. Permanent magnets are used in certain measuring instruments, such as moving-coil instruments, fridge magnets, etc.A temporary magnet is a material which retains its magnetism providing any external magnetising force continues to be applied. For example, when the current passing though a coil wound around that material flows, it will continue to act as a magnet, but once the current is turned off it will lose that magnetism (or most of it!). Temporary magnets are used to manufacture relays, transformer cores, etc.
