Ampere's Law and Related Phenomena

Description
Ampere's circuital law and its application are explained.The law is applied to a conductor carrying current and solenoid.Using a solenoid of few turns, the pattern of magnetic field is examined by using iron filings. Current is passed through a large solenoid and an iron rod is brought near it to show the characteristics of magnetic field of a solenoid.Kelvin Water Dropper experiment shows how ionized water and gravity generate the large potential differences .The theory and experimental demonstration is captivating.
