Hey guys I want to build electromagnet which can lift up to 3 kg from 26 gauge copper wire, 12V battery (bike), so how many turns should I do and what will be length and radius of the solenoid?

In summary, to lift 3 kg with an electromagnet made from 26 gauge copper wire and a 12V bike battery, you will need to experiment with the number of turns, length, and radius of the solenoid. Generally, more turns will result in a stronger magnetic field, but be careful not to overheat your battery. It is also important to use a thicker wire and a voltage regulator to prevent damage. Happy building!

Welcome to the PF. 
A solenoid is not a very efficient electromagnet for lifting weights. You want the magnetic path to be fairly "closed" when lifting an object. You do that by presenting both poles at the same time on the same plane, and attaching a ferrous piece of metal to the two poles, hence closing the magnetic path...

Hi there! Building an electromagnet can be a fun project. The number of turns and the length and radius of the solenoid will depend on a few factors such as the strength of your battery and the strength of the magnetic field you want to create. Generally, the more turns you have, the stronger the magnetic field will be. However, too many turns can also lead to overheating and damage to your battery.
To lift 3 kg, you will need a strong magnetic field. I would recommend using a thicker wire than 26 gauge, as it may not be able to handle the current needed for a strong enough field. A 12V bike battery should work, but make sure to use a proper voltage regulator to prevent overheating.
As for the number of turns, you can start with around 500 turns and test the strength of the magnetic field. If it's not strong enough, you can add more turns. As for the length and radius of the solenoid, it will depend on the size of your battery and the space you have available. Generally, a longer and thinner solenoid will create a stronger magnetic field, but it may also be more prone to overheating.
I would recommend doing some research and experimenting with different configurations to find the best one for your specific project. Good luck with your electromagnet!
1. How do I build an electromagnet that can lift up to 3 kg?
To build an electromagnet that can lift up to 3 kg, you will need a power source, a copper wire with a gauge of 26, and a ferromagnetic core such as iron or steel. The steps to build the electromagnet are as follows:
- Strip the insulation off both ends of the copper wire.
- Wrap the copper wire tightly around the ferromagnetic core, leaving about 10 cm of wire on each end.
- Connect one end of the wire to the positive terminal of the power source and the other end to the negative terminal.
- Turn on the power source and test the strength of the electromagnet by placing small metal objects near the core.
- If the electromagnet is not strong enough, you can add more layers of wire or use a thicker gauge wire.
2. What is the best type of wire to use for an electromagnet?
The best type of wire to use for an electromagnet is copper wire. It is a good conductor of electricity and can easily be shaped into coils. The gauge or thickness of the wire also plays a role in the strength of the electromagnet, with a lower gauge wire being thicker and able to carry more current.
3. How much weight can a 26 gauge copper wire electromagnet lift?
The weight that a 26 gauge copper wire electromagnet can lift depends on the strength of the power source and the number of wire coils wrapped around the ferromagnetic core. Generally, a 26 gauge copper wire electromagnet can lift up to 3 kg with a strong enough power source.
4. Can I use a different type of metal for the core of the electromagnet?
Yes, you can use a different type of metal for the core of the electromagnet, as long as it is ferromagnetic. This means that the metal can be magnetized and will retain its magnetism even after the current is turned off. Common ferromagnetic materials include iron, steel, nickel, and cobalt.
5. How does an electromagnet work?
An electromagnet works by using electricity to create a magnetic field. When an electric current flows through a wire, it creates a magnetic field around the wire. By wrapping the wire into a coil and passing a current through it, the magnetic field becomes stronger. The ferromagnetic core inside the coil becomes magnetized and can attract or repel other magnetic objects, depending on the direction of the current.
