The more turns of wire in an electromagnet the stronger the magnetic field.
The number of wraps of wire in an electromagnet affects its magnetic strength. Increasing the number of wraps increases the number of turns in the coil, resulting in a stronger magnetic field when current passes through the wire. This means that more wraps generally lead to a more powerful electromagnet.
the more times you wrap it the stronger it will become. less wraps less powerful
You typically wrap a nail in an electromagnet 50-200 times to create a strong magnetic field. The exact number of wraps depends on the strength of the applied current and the size of the nail.
the electromagnet is in the track then there are permanent magnets on the very bottom of the train on the part that wraps around the track
A magnetic field is induced by pushing current though a wire; so you could consider a straight wire an electromagnet. Using more coils will strenghten the electromagnet, though, so a straight wire version will be very weak comparitively.
If there are only a few wraps, the magnetic field will be weaker than if there are many more wraps.
Three things affect the strength of an electromagnet.The number of turns/wraps of wire.The amount of current flowing through the wire (which is determined by the voltage and the size & kind of the wire).What the core is made of -- the core is the thing the wire is wound around. It will be much stronger if wound around metal than air. Iron makes a better core than most other metals.

It will take approximately 40 minutes to make the minimum of 360 wraps for the party. This can be calculated by dividing the total number of wraps needed (360) by the number of wraps made per minute (9).
CamoWraps are high strength vinyl vehicle wraps used on trucks, SUVs, ATVs, and boats. They offer protection from weather elements, camouflage for outdoorsmen, and a unique method of personalization.
Shawls and wraps can be purchased from a number of retailers online. Some examples of retailers that carry shawls and wraps online are Overstock, Amazon, and Light in the Box.
One way to increase the strength of a copper electromagnet is by adding another coil. Another way is by wrapping the copper coil around a nail made of iron.Adding more loops to the wireWrapping the copper wire around an iron nailIncreasing the current
