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 is the nail in an electromagnet?
The nail in an electromagnet is the core of the electromagnet. It is there to provide the magnetic lines of force a "highway" to get from one end of the coil to the other end through the middle of the coil. The magnetic lines of force "like" the nail because it is a ferromagnetic material. They can travel through it very easily - and they do! The nail also provides the "working end" of the electromagnet. The magnetic field lines emerge from the nail, and then act on what is there. If you are, say, doing a separation experiment removing steel tacks that are mixed in with small brass nails (brads), the tacks will stick to the end of the nail at the "working surface" or the pole of the electromagnet.
What do you loop a wire around to make an electromagnet?
steel =========== Most often, a soft-iron core, which becomes the actual magnet when the current is flowing in the turns of wire around it. ------------------------------------ An iron core. The simplest electromagnet can be made by wrapping an iron nail (common construction nail) with a copper wire (insulated not bare copper) and attaching both ends of the wire to a battery. The more wraps and the higher the voltage the stronger the magnetic field produced. Note: an electromagnet can only be made with DC electricity, as AC electricity will constantly reverse polarity 50-60 times per second!
How can the magnetic field strength of an electromagnet be reduced?
Either increasing the size of the current (in amps) or the number of turns of wire wrapped around the core will make a stronger magnet. A larger current will make a stronger magnet (up until too much makes the wire melt!). Increasing the voltage forces more current through the electromagnet.
What effect does decreasing the number of coils around the nail have on the strength of the electromagnet?
Decreasing the number of coils reduces the strength of the magnet.
Which is a stronger electromagnet- a nail or a bolt?
Bolt
When you make a homemade electromagnet with wire and a nail and a battery does stripping the wire that is coiled around the nail make the electromagnet stronger?
No, this will stop the magnet from functioning and is the same as using a short thick wire instead of a long coiled wire.
How do you make a electromagnet stronger?
For a simple copper wire around iron nail electromagnet, increasing the number of rounds the copper wire makes around the nail will increase the electromagnet's strength. Also, increasing the voltage applied(adding a battery) will increase the magnetic field.
Electromagnet does the number of times you wrap the wire around the nail affect th strength of the nail?
the more times you wrap it the stronger it will become. less wraps less powerful

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