Step 5 Water valve solenoid

this coil is another plastic covered one and it comes from a solenoid that opens a water valve{ washing machines and dishwashers maybe likely sources}.
in it i have glued a section of a steel bolt because i didnt have a magnet of the proper diameter to put in it but to magnetize it i just slapped a hard drive magnet onto the bottom end(it doesnt matter which one but then it becomes bottom}.
your getting the idea now plug it into the amp and twang away.
