Electromagnets are stronger and weigh far less than permanent magnets.
It makes sense that since some magnets are called "permanent magnets," other magnets should be called "temporary magnets." But since when did English make sense? We usually call them "electromagnets" instead. Electromagnets are used in most electric motors, and cranes that lift scrap metal. They're also used in relays and the write heads of tape recorders (including video tape recorders).
Electromagnets' magnetism can be manipulated. Electromagnets can be magnetised and demagnetised by passing electric current. Therefore they are used in motors- which works when the coil is magnetised by passing an electric current. It is also used for cranes.
An electromagnet's magnetic field can be controlled by adjusting the current flowing through it, allowing for dynamic control of the magnet's strength. This flexibility makes electromagnets suitable for applications such as magnetic levitation, electric motors, and electromagnetic cranes, which cannot be achieved with regular permanent magnets.
But they are! You can find lifting magnets based on permanent magnets all over in machine shops.
Electromagnets are commonly used in junkyard cranes to lift and move heavy metal objects. They are also used in MRI machines in hospitals to produce detailed images of the human body. Electromagnets are found in speakers and headphones to convert electrical signals into sound waves.

Electromagnets are cool because they are reversible and can switch on and off, allowing for precise and rapid control. They are also lightweight and portable compared to permanent magnets. Additionally, electromagnets are versatile and can be found in many different applications, from MRI machines to speakers.

Yes. There are huge electromagnets suspended from cranes that could do that.

Electromagnets have several uses. They are used in cranes to pick heavy metal objects, to lift tiny metal scraps from wound by doctors, motor and generators, electric bells, loudspeakers, etc.
Many electrical and electronic devices use electromagnets, including telephones, sound speakers, maglev trains, junkyard cranes, and doorbells. Electric motors create an electromagnetic field around a permanent magnet, as do the generators used to create electric power.
Usually in junk-yards handling scrap iron and steel. Only problem is some steel alloys- like stainless, are non-magnetic not attracted to the electromagnets.
sandhill cranes have no permanent home. they are migratory
