Aluminum Foil Magnetic Force
1,253 wordsSummary of Investigation An investigation was carried out to find out the relationship between the force created in a wire (or solenoid) when current flowed through it and the force from gravity. This was investigated by connecting a solenoid up to a variable power pack and then placing a light ring of either copper or aluminum around the solenoid. When the current flows through the solenoid, a magnetic force created from the solenoid should make the ring 'jump' up or levitate. When carrying out...
