What is the magnetic effect of electricity?
What to use
Long nail, steel rod or metal knitting needle, thin insulated wire, power source (initially set at 2V), paper clips, a range of other objects some of which you believe will be attracted to a magnet and some which might not.
What to do
- Wrap thin insulated wire around a long nail or steel rod many times.
- Connect the coil to a power supply.
- Turn the power on. You have created an electromagnet.
- Use your observation and some additional research if necessary, to answer these questions.
