science project - electromagnetic flux

Two solenoids made of single-strand copper wire wound on wooden spools with a large-head iron nail as the plunger are placed alongside. The solenoids are connected in series and powered by 6V DC source. When the coils are energized an induced electromagnetic field is produced and magnetize the plungers creating magnetic pole on both ends. The plungers attract each other because of opposite poles. When the power connection of one of the solenoids is reversed, the plungers repel each other. This project demonstrates electromagnetic flux can be produced by direct current, using copper wire and ferrite material. There are many industrial control and switching circuitry applications using electromagnetic force.

can u pls give the details of the connection

[FunSciEdu]

@ashlpurple Sure! I'd be happy to email you the schematic diagram.

uhm wen testing partially d projct, does the nail suppose to be magnetized or somewht be sticked to to the solenoid?

[FunSciEdu]

@jvermillion24 When current passes through the coil the nail should behave like a magnet. The stronger the current the stronger is the magnetic force. You can test the existence of magnetic field by a paperclip. The material of the nail also counts. The more iron content the stronger the field.

tnx so much for the diagram and sorry for im quiteslow at understanding this. but could i ask for labels?im confused as to wat the broken lines meant and there were only 3 dots which i assumed that those are circles on the top but there are four of them on your video?

[FunSciEdu]

@jvermillion24 Thanks for asking. Sure I will email you the diagram.

@FunSciEdu can i have d circuit diagram too pls? at my email vermillion_li@yahoo.com

There is, of course, engineering calculations on the gauge size of the wire and the number of turns in order to get certain magnetic force to get a job done. Here, for the fun of it, the number of turns does not matter much. One thing worth mentioning is that single core copper wire is used, not multi-stranded wire, for better efficiency.
