hi I passed by text in the book which talks about ,making tow poles in this experiment , but I cant find anyone make tow pole here is the text: All you have to do to create an electromagnet is connect a battery to the ends of the coiled wire, making a closed circuit. When current flows through the wire, the piece of iron it’s wrapped around starts to behave like a magnet, *with the south pole at one end and the north pole at the other end*.
How did you hold it? I was using a 1.5 volt battery and it kept burning me and it didn't even pick up the paper clip even though I did around 15 or 16 coils around it
Would it be stronger if the wire was not insulated so that the wire was touching the nail. i get the idea is to make it a magnet just by the solenoid however I was watching other videos that picked up more with the same size battery and what appeared to be even smaller wire.
If the wire were touching the nail, you'd just have one big chunk of metal with current flowing through. Keeping the wire insulated ensures that the current is looping around the iron core, which is what creates the magnet. A different gauge wire would have different results, depending on the wire's resistance (more current flowing through = stronger magnetic field).
@@danniellecounce8756 I can't speak to what someone else said, I just know in my experience it doesn't work if there's not at least some coating on the wire. Maybe I'm wrong - I'm no expert, by any means! :-)
@@angelafranz6409 me either my neice had to do the experiment and it was late and we didnt have a battery or paper clips and thanks to walmart nolonger being 24 hrs we just watched others do the experiment. However ive never done this as far as i can remember but i was just curious because it seems with all the work of wrapping, connecting the battery, and wires it would be much stronger
The most common issue is a weak or dead battery, so check your voltage if you have a voltmeter. Next, make sure the ends of your wire are bare, and touching the ends of the battery (metal to metal). Make sure you're using an iron nail, not steel (steel is difficult to magnetize due to the alloy components).
No, because then the foil & nail would just act as one big piece of metal. Having insulated wire is what makes the current flow in a loop, creating the magnetic field in the nail.
i did use aluminum once because i thought it was coil wire since it was covered in the coating. I did use it without knowing and did pick up 1-3 paper clips for me
@@fizz.mp4756The reason that the wire needs to be insulated here, and in solenoids, and speakers, and motors, etc. is to force the current to take a much longer path, and spend much more time in a much _smaller volume of space_ so the current density is much higher. If you allow the current to go in a straight direct line from one end to the other... which is exactly what it will do if you don't stop it with the insulation... the resulting magnetic field will be much weaker.
Yes - there are a few things that might lead to your battery getting hot quickly. For example, if you have a high-voltage battery (like a 9 volt) or a thicker wire (with less resistance), the current will be flowing very fast and things will heat up quickly.
@@angelafranz6409 thank you, i am also wondering since the battery got very hot is its still like reusable for like TV remotes and such stuff or will that just damage the battery further?
@@xoxo45748 it should still be usable. The battery would drain faster from getting hot (it's using up energy faster than usual), but as long as you didn't keep it connected very long, it would still be just fine.
@@xoxo45748It's literally a short circuit. The battery is supplying 100% of the current it possibly can. If you add a resister to the circuit to limit the current your battery won't heat up as quickly.
If I understand your question correctly, you're asking about the reaction when using a bare wire? In that case, you would still be creating an electromagnet but the wire would heat up VERY quickly! This could lead to potentially injury in the classroom, which is why we always use coated wires when working with students!
@@angelafranz6409 I love that you actually reply. WIll you encourage me to make content in some way? I wonder what would happen with a extention cord or a large spool of wire would this somehow end up with an induction magnetic metal melter happening?
Thanks 😊 for the video

I don't go to your school but I have to make an Electromagnet for a Physics project, thank you for this video.
Nonsense
You also use only iron nail and peper clips 😅
Thank u it has really really helpful
hey i love the video it is really cool i think that your RUclips channel will be very poupler
Your channel will become the best one on youtube!
Thank you!
How did you hold it? I was using a 1.5 volt battery and it kept burning me and it didn't even pick up the paper clip even though I did around 15 or 16 coils around it
be sure about your battery is charged and the wire is copper
@@ubadaashaeib8237 i'm pretty sure it was charged and the wire was 100% copper
Did the wire you used have insulation on it because if it didn't it will burn you and you will not be able to hold it very long
no it didnt
anyway i couldnt care less now@@arcturusbbqsausagemaking2435
I qm not in your school but i had to build an electromagnet and i thank you
Same lol
Let me guess your in 11 grade for physics
@@ryshy02o44 im in 8th grade physics lmao in egypt
bro im in grade 5
@@ygjuniorrr1888 same lol
Instead of paper clips, what else can u use
For 3. (1) Does adding more current simply mean using a battery with more voltage?
Very helpful thank you
How would you calculate the strength of your electomagnet's magnetic field in Teslas?
Very nice
Your video was super helpful! thank you!
You're so welcome!
@@angelafranz6409 This really is a great video thank you!

@angelafranz6409 If you don't use insulated wire it will burn your hand you won't be able to hold it very long it hurts ...very good video
What factors affect the strength of an electromagnet?
The thickness of the wire
The amount of turns you make on the iron nail
The power(voltage) of the current
Ours isnt working! What could be some reasons so that we can troubleshoot?

Make sure you're using an iron nail, not steel (steel is difficult to magnetize due to the alloy components).
I have a question does the amount of volts have to be 7.5 or more i tried it with a double AA battery and i keep burning myself it has 1.5 volts
Me too i started mini fire still pretty cool though
@@hi-lk4up Yikes!
very nice,,,mike uk
You need more loops
thank you

My battery was brand new and it got hot almost instantly, is that normal?

What is the voltage of That battery
that penmanship tho-
Thank for telling
thank you for this trivia
Can I use a thick wire
what if non-insulated wire is used?
it would give the same result but insulated wire is way safe
So whether the wire is not wrapped what's going to be the reaction

Use a battery 🔋 holder
Can I do this using a long screw?
I would say yes, assuming that there’s no coating covering the screw.
Are they any other wire that i could use to do this project??
yes you can use any wire but copper wire produces the best results. Whatever wire you use make sure its insulated
can we use any voltage of battery
IRON NAIL ? Or steel nail ? Ha Ha
Iron nail h wo
damn i need a 6 volt
no
Boo!
