You can do a lemon battery experiment. You insert a galvanized nail in one side of the lemon and on the other side insert a copper wire. Connect a volt meter to the nail and the copper and it will show the presence of an electric current.
science electronic working model
its means that you r going to be working in a group of people to do your science project
he is working on a science project
dam will be good idea
pulley I vote for a working volcano complete with dinosaurs around it
There are many try the link below.
How to make a model of an energy class science project
initially when current pass through the filament
well i am working on a science fair project and so far yes
Put a battery in a holder then press a button
Yes- you have suggested a correct working definition for a conductor.
When you flip the switch to turn off the electromagnet, the flow of electric current stops, which in turn stops the magnetic field from being produced by the coil. The magnetic field is generated by the flow of electric current through the coil, so cutting off the current stops the magnetic field, causing the electromagnet to stop working.
