Cranes with electromagnetic lift are known as electromagnetic cranes. Such cranes are used widely in lifting and moving scrap metal. Even in a production line of many products, electromagnetic cranes are used to lift and move the metal objects. Electromagnetic cranes are particularly simple and have many advantages over other lifting tools. They are both faster and easier to work with.

Electro magnets can be used to attract metals temperarily while permanent magnet would be used for compasses.
The advanateg would only be in scrap yards involving the electro-magnetic handling of ferrous-metals. unforutnaely stainless steel is non-magnetic . there are electric cranes which run on bridge-like st ructures but these are not electro-magnetic. these have some tactical advatages of very precise control, solenoid brakes which are electro -magnetic, and safety and low noise . also they do not pollute =these are normally used indoors in factories and warehousesl. they usually have(dead man) controls which revert to neutral or stop if the operator lets go they spring back tothe central positin again aiding safety.
Electro magnets differs from permanent magnet because it requires electricity. A simple electro magnet consists of an iron rod wrapped in a coil of copper and when electricity flows through the copper, a magnetic field is formed.
Electromagnets use electricity to create a magnetic field, which can be turned on and off. They are typically stronger than permanent magnets. In contrast, permanent magnets, like those made of iron or nickel, are always magnetic without the need for an external power source.
Electro magnets can be very useful to carry heavy loads of iron and metal from one side of a factory to another. Electro-magnets are formed by shooting electricity through a coil of copper.
They can be used in Junk yards to pick up junk. They can be used in a Dentist.

Electro-magnets
Natural magnets are not strong enough to lift heavy loads typically encountered in crane operations. Man-made magnets, such as electromagnets, can be controlled and adjusted to generate the necessary magnetic force to lift heavy objects more efficiently. Additionally, natural magnets can lose their magnetism over time, making them unreliable for industrial applications.
of course not.

Yes, because electromagnets can lose their magnetism.
Yes, electromagnets itself is an artificial magnet.
Electromagnets are used to make electric power because magnets are a type of electricity,and electro is at the front.
If your computer is using a CRT (instead of an LCD or plasma screen), the electromagnet is causing the electron beam to "bend" as it passes across the screen to make the image. If your computer uses a hard-drive, electro-magnets are used to position the read/write head, to spin the disk and to write to the head. An electro magnet is also used to spin the motor of the cooling fan(s). Electro-magnets are part of your automobile's electrical system as well. The starter motor uses electro-magnets as do all electric motors, the ignition coil is little more than specialized electro-magnets, the automatic door actuators are electro-magnets as are the injectors and any relays. Electro-magnets are everywhere, you just need to know where to look.
