Experiments About Electricity and Magnetism
What materials make the best conductors of electricity? Does the amount of coiled wire layers increase the pull of an electromagnet Can you make a compass out of a paper clip? Can you see a magnetic field? What methods are the best for demagnetizing a magnet? What fruit electrolyte gives the most voltage? Can you measure the magnetic fields of different types of magnets? What’s the difference between parallel and series circuits? Can you transfer copper molecules to a steel key? Can you make an electric alert “rain buzzer?” What coin arrangement makes the best “coin battery?” How can you make an electric telegraph? Which make of battery will last the longest? How does “magnetic induction” work? Can you conduct electricity through a salt solution? Sugar Solution? How can electricity be made through motion? What materials will a balloon pick up best by static electricity? How can I demon-strate “escape velocity” with alnico magnets and a steel ball? What electrolytes conduct electricity the best? Which batteries will last the longest on a given electrical light?
