Magnetic Hill is a gravity hill located near Leh in Ladakh, India. The hill is alleged to have magnetic properties strong enough to pull cars uphill and force passing aircraft to increase their altitude in order to escape magnetic interference. In reality, the effect is an optical illusion and there is no magnetic disturbance in the area at all. (as taken from Wikipedia)
The illusion works very well even if it not magnetic. We saw persons playing around with their vehicles and at one instance we saw a car being pulled uphill, a very nice illusion to witness and and see.
