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.

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.


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