Engineering Electromagnets!
Posted by Joshua Bartosiewicz- A battery and a copper wire coiled around an iron nail are used to create a magnet!
- Picking up paperclips with the magnet.
- “Wow, that’s a strong magnet!”
- Creating a coil or solenoid for the electromagnet.
- More coils!
- “Woah, I didn’t expect it to work!”
- A strong magnet being used to hold other nails.
The 8th grade was able to build their own electromagnets in the science lab! The students have been learning so much about electricity, magnetism and electromagnets (the movement of charged particles in a coil can create a magnetic field). For this lab, the scholars were given batteries, copper coils, iron nails and paperclips and were asked to build an electromagnet. They had a general understanding of the material but after completing this lab, there was no question on how electromagnets function. Students were able to play around with their designs by using different types of wire, changing the number of loops around the iron nail (more loops would make a stronger magnet due to the overlapping magnetic fields created from the charged particles flowing through the wire which is from the battery), and using different types of batteries. In the end, the 8th graders thoroughly enjoyed creating their own magnets and comparing the strengths of their magnets to each others.
