Help needed with my project (electromagnetism)
Posted: Fri Feb 12, 2021 10:14 am
I am a teacher and I am trying to create an electric door bell .
This is a project that I am going to share it with my class next week, but I unfortunately I amnot able to make it work so far.
I have make an electromagnet that normally should attract the metal and in this way the circuit will be disconnected. The electromagnet works, but when it is connected with a battery but when it is connected to the circuit nothing happens.
So, I decided to change battery in the circuit. Firtsly, I used a 4,5 Volt battery and now I am using a 9 volt battery.
Now, the electromagnet doesn't work, but I noticed that sparks has been produced in a specific part of the circuit. What does this mean?
Could you please help me to find what I am doing wrong?
Thank you very much!
