To make our electromagnet stronger we can give it an iron core. This will boost the power of our electromagnet and give us better results. This is as simple as winding the copper enamelled wire around an iron nail and securing it with sticky tape. When you connect it to a battery you will a have a stronger electromagnet. There are some simple things we can do to make our electromagnets stronger.
To make electromagnets stronger we must do the following:
- Add more windings
- Give it an iron core
- Increase the current flowing through the wire
