idea, you keep the metal core longer, so it goes into a drill, then wind up the copper, and then cut the piece to length. But overall simple stuff, thanks for sharing.
Great how to. Drawing schematic on connector board makes it easy to follow. Fast way to remove enamel insulation from magnet wire! Hope to see more from you.
Nice project, looking at the design I think the coil is maybe around 10 ohms, so maybe 1.2 amps which is ok for 1000 turns of 26 gauge you say you use. With that size battery you should use some current control ie an online fuse and you should also deal with the large back emf generated at switching since induced voltage is proportional to rate of change of current and it will be high, this would also help to eliminate rf interference when switching
Carl men, I could not find something exactly 5 kg when I shot the video...but it can lift upto 5-5.5 kg . It is important to use a battery or power supply that Can supply enough current.

Hi, I am a power plant engineer. Making videos such as this is a good thing to increase knowledge. But let me add some safety inputs, you need to ensure before working in any system to disconnect first the energy supply (e.g. battery) regardless if the system switch/breaker is open. Even if it is very obvious, always consider electrical system as live ones. The 12V DC does not that give you good shock, but for some it will hurt, but still, regardless of voltage and current of the supply (if mechanical, pressure, etc.), be safe always. Connect power supply after what you are doing, especially in industrial and power field, there LOTO and verification with partners will take effect. Practice of safety starts from small things you are doing.
Thank you very much for your inputs and suggestions. Will implement in future videos. And I have also learning many safety practices working as a instrumentation engineer now. I was a student back then. Thank you.
Hi, great video mate, but I have some queries... How does length and diameter of effect the electromagnet strength? I understand more no of turns are better, so does a smaller dia. core is better? Also what is better having a single layer of coil over a long core or multiple layer of coil over a short core. Thanks.
Longer will be better but it will waste lot of wire Smaller dia will be better to but it wil become very hot after a few minutes due to the resistance of the wire So the combination between long wire and reasonable dia will give the best performance. And about the layer because the wire is long so we need to make layer over layer, it just effects a little bit so don't worry.
I don't know much about electromagnets but need to make a tool for a specific task. I have snapped a half shaft on my land rover and need to remove the broken end. The hole I need to pass the tool down is about 1" in diameter and 3' deep. The magnet would need to be as strong as possible to pull on the broken end to disengage it from the splines in the diff. So my questions are does the size of the core iron matter and also what gauge wire should i use for maximum strength in the space I have available? I was going to try and attach it to the end of a broom handle.
Hello. I'm trying it with 0.35mm coil wire. but when I give current, it is not magnet. What could be the problem? Does the copper wire you use have a feature?
By the way for those who don't know, the so-called magnet wire is enameled wire. The basic wire that is used in everything. Coils, transformers, all your motors, armatures, stators. You got the idea. Oh by the way. this is plane science that what makes for a strong magnet is lots of electric currents. The more current the more magnetic field, that is aside from numerous windings of course. This means the thinner the wire, the more resistance,. More resistance means what? You want a serious magnet? use thick wire, lots of voltage and current. And by the way, keep it DC. 200 volts DC and you will be cooking. Don't hurt yourself.
@ chase kendig.. magnetic flux . lines of force NEVER cross, lines of force are CONTINUOUS, lines of force ALWAYS form individual CLISED LOOPS around the magnet ,lines of force have a DEFINITE direction from NORTH to SOUTH , lines of force that are close signify a STRONG mag. field , lines of force that are far apart signify a WEAK mag. field.
From the place I bought , they sell in grams. I had purchased 100g (if I remember correctly). Might be around 30-50 meters. I don't remember exactly . Sorry.
Hi Techno, I am trying to make a permanent magnet remagnetiser using 2 electro magnets for remagnetising slot car motor magnets, I have had some success but the electromagnets aren't strong enough, is it better to have a long core with less layers of windings or a short core with more layers of windings or does it not matter? I have used 260 grams of 14AWG wire around a 200mm long 16mm diameter iron core but it is feeble compared with your results, any help would be greatly appreciated.
Please help me understand how you're getting 8.7 ohms resistance? do you mean across all the wires or just in the coil? from the links and info provided, i got an answer of 0.153 ohms
if you have that kind of constant resistance from the first place your wire will get heated up and burned with just a few minutes because of hight current. its so simple use multimeter to measure your resistance in the coil before supplying
What kind of power are you running through this? Is it not dangerous picking up the whole thing bare hands when those joints are not properly insulated?
No because it is magnet and magnet don’t repel metals… but it will repel or attract other magnets(either permanent magnet or electromagnet) depend on the orientation of this electromagnet relative to other magnets that is near it.
heres an idea. get an iron rod about 2 inches longer than needed. rol paper put ends on and leave extra length on on side. then when you wind the the (magnet wire) coated copper wire just hook it up to a cordless drill. those 900 wont be so hard. just estimate the turns with the example he shows
thanks a lot for you reply i have two question (1) 36 gauge is very thin in 36 gauge and tiny compare with 26 gauge wire so how the resistance is very high in 36 gauge (2) if i use 230 v supply which wire and how many turns and iron rod size will capable to handle? kindly get back to me with your view on this
Arun v , the resistance of wire is given by (resistivity of wire)*(length of wire) divided by area of cross section. for 220 v supply... make sure your coil impedance is high enough so that the max current through wire is not exceeded. www.powerstream.com/Wire_Size.htm above link is for max current and resistance per km for particular gauge of wire. You do the the math and find the exact wire you want for your application. You might revist my channel any time. Thank you!

Magnet wire is usually insulated with a thin type of glass. Also I dont think he is using that much power to be anything to worry about
6 or 12 volts is no shock hazard. But 600 volt spikes are generated when switching the magnet off. Unpleasant but not dangerous...

No. It must be DC current.
