Electromagnets can be controlled by adjusting the amount of electric current passing through the wire coil. Increasing the current strengthens the magnetic field, while decreasing the current weakens it. Additionally, the direction of the magnetic field can be controlled by changing the direction of the current flow through the coil.
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.
"electro magnets" are magnetic ONLY when electricity travels through a coil of wire surrounding them. "Magnets", as you state it, are permanent magnets and remain so independent of and not dependent upon any additional electrical charge.
Electro magnets are magnets created by wrapping a conductive wire around a core and passing an electric current through the wire. They produce a magnetic field when the electric current flows through them, which can attract or repel nearby magnetic materials. Electro magnets are used in a variety of applications such as electric motors, speakers, and magnetic resonance imaging (MRI) machines.
Most electric motors use electromagnets because they can be easily controlled by adjusting the electric current flowing through them, allowing for precise speed and torque control. Additionally, electromagnets provide stronger magnetic fields compared to permanent magnets, making them more efficient for many industrial applications.
Cranes use electromagnets because they can be controlled and turned on/off easily by adjusting the electric current. This provides flexibility in lifting and releasing materials. Permanent magnets, on the other hand, have a fixed magnetic strength and cannot be adjusted or controlled.
Electro-magnets
of course not.

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.
Yes, because electromagnets can lose their magnetism.
Yes, electromagnets itself is an artificial magnet.
For a simple electro-magnet use a DC supply.
Lots of things do. For example, relays. (The electronical component)
A loud speaker can use electro magnets and i hope this helps =)
(electro) Magnets in the "track".
