Purpose:

To study the effect of spacing of the shelves on the power of an electromagnet

Apparatus Necessary:

* A great iron toenail (around 8 cm)

* A copper mineral wire (15 cm)

2. Vernier Logger Pro

* Magnetic Field sensor

2. Battery

* Switch

2. Sand Newspaper

Background Theory:

Some alloys such as dime and flat iron can be magnetised using an electromagnet. The effectiveness of the electromagnet depends on different factors which include the current, no . of transforms per unit length as well as the core of the magnetised metallic. In this research, I will examine the effect of spacing between your turns in the copper coil wound throughout the iron fingernail.

Variables:

Controlled Variables| Dependent Variables| Independent Variables| Length of Copper WireCurrent in the copper wireCore of the electromagnetArea of Cross section of the iron coreThe point where magnetic field strength is usually measuredTime| Power of the Electromagnet| Spacing in the turns of copper line

How the parameters are handled:

1 ) The length of the copper wire is kept constant in 15 centimeter for all trials 2 . The present in the water piping wire is definitely kept constant by keeping the voltage inside the circuit regular as the copper line has a constant resistance. 3. The area of cross part of the nail is kept constant at a particular worth throughout the experiment as a sole iron fingernail is used. 5. The point at which the magnetic field strength is usually measured is usually kept in 5 centimeter below the reduce tip with the iron toenail. 5. Enough time for carrying your experiment is usually kept regular at 15 mins.

Speculation:

As the distance between the consecutive coil raises, the number...
