Iam trying to the max voltage produced from a magnetic being dropped through a wire with a relationship on the height the magnet is dropped from. i know that emf=-v= n(partial derivative of magnetic flux). but i am not sure how to relate this to the height the magnet is dropped through a solenoid (wire coil). it would be amazing if anyone could me with this formula. i tried finding the velocity with ki, ko and ui, and uo, but i don't know how to join them. i am dropping a magnet through a wire from varing heights and measureing the max voltage that is measured. i am trying to derive the ideal equation for this procress
