 P: 1 i've searched all over the web and would you believe it, THERE ISN'T A SINGLE PLACE THAT EXPALINS HOW TO MAKE A SIMPLE ELECTROMAGNETIC BELL! i need to make one for this marking period, but i'm not quite sure of the materials needed. i'd appriciate it if my question will be answered. my physics textbook doesn't answer this, my teacher, for some odd reason, refuses to tell me (i bet he doesn't know it himself!), my mom doesn't know, my dad doesn't know, my friends don't know AND NONE OF THE SEARCH ENGINES ON THE WEB CAN DIRECT ME TO A DECENT SITE! I'M GOING CRAZY! H*E*L*P!!!!!!!!!!!!

I can't believe somebody sells kits for something this simple. I built one of these things from scratch when I was about 11.
All you need to do is wrap a few hundred turns of magnet wire around a nail or bolt to make an electromagnet. Then have a small steel strip mounted in front of it, with a little weight on one end to use as a striker. Route the magnet wire to one part of the striker, and the other end through your switch and battery to another nail that the striker rests against when not attracted by the magnet. When the magnet is energized, it pulls the striker against the bell and also breaks the circuit so that the strip springs back.
I can post a small diagram if needed.

The device described by Gokul becomes a ringer (instead of a bell) when you attach it to a source of alternating current.
