Step 2: Making the coil
Stack the magnets.
Wrap around them the enameled wire.
Make about 10 loops. Leave about 10 cm of free wire at both ends for connection.
To make the coil rigid, put some drops of glue with the glu gun, and then use the glue gun tip as a brush: you want to cover the whole coil with a very thin layer of glue to keep the loops in place.
Remove the magnets inside.
Carefully remove the paper from the inside of the coil.
You should end up with something like this:
