To separate materials made of metal in the scrap yard.
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.
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.
One is temporary, the other is more or less permanent.

Every machine with a motor has a magnet. If you plug it in, it has a magnet. If you put in batteries or recharge it, it has a magnet. An automatic pencil sharpener uses magnets. A computer printer uses magnets. A refrigerator motor uses magnets. An electric razor uses magnets. A fan uses magnets. Hair cutters use magnets. Nose clippers use magnets. Look around your room and see what else uses a motor.
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.
they have magnetic properties that weaken with time.
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.
