Is an electromagnet made of a coiled wire and a metal bolt stronger than one made with a wire alone?

Yes. An Iron core electromagnet has a stronger magnetic field then a coil. The magnetic flux is condensed and travels through the iron core with little resistance, while air provides much greater resistance.

Why is an electro magnet better than a normal magnet?
An electromagnet is made by wrapping coiled wire around a piece of metal. When a current is applied, it creates a magetic field. The main advantage is that an electromagnet can be turned off by breaking the circuit. That's how those big magnet cranes at junkyards can let go of the metal. You can easily make a fun electromagnet project that kids love. Just coil a wire around a bolt, and hook up the ends to both sides of a battery. A 6 volt flashlight battery works great. More coils means a stronger magnet.
What does an electromagnet operator do to release metal attached to the electromagnet?
burat
What does the electromagnet pick up?
Ferrous metal.
What metal would you use for the centre of an electromagnet?
iron
When were electromagnets invented?
In 1825 an Englishman named William Sturgeon and Francis Watkins made the first electromagnet . They used a horseshoe shaped piece of iron, coiled 16 loops of wire around it, and ran electricity through it. It could pick up 9 pounds of metal.

How does the strength of a wooden core electromagnet compare with that of the iron core electromagnet?
Electromagnets consist of wire coiled around a core. The core can be anything from air to a nail or even a pencil. Since electrons flow freely through a conductive core (like a nail), an electromagnet made with a metal core will have a larger magnetic field (and thus be stronger) than an electromagnet with a wooden core. The strength of an electromagnet is related to the number of times the wire is coiled around the core and the distance the wire covers across the core. The more coils wrapped closer together, the stronger an electromagnet will be. The amount of voltage running through the wire also plays a role in an electromagnet's strength. More voltage means more electrons moving through the wire and thus a stronger magnet.
What makes an electromagnet powerful?
more coils around the metal object, thicker wire being coiled, and more electricity going to the wire.

How does a door bell works?
A chime doorbell uses a specialized sort of electromagnet called a solenoid. A solenoid is just an electromagnet where the coiled wire surrounds a metal piston. The piston contains magnetically conductive metal, so it can be moved backward or forward by the electromagnetic field.Reference:http://home.howstuffworks.com/doorbell3.htm
