			A metal bar of mass '''M''' and length '''L''' slides with negligable friction but good electrical contact down between two verticle metal posts. The bar falls at a constant speed '''v'''. The falling ball and verticle metal posts have negligable electrical resistance, but the bottom rod is a resistor with resistance '''R'''. Throughout the entire region there is a uniform magnetic field with magnitude '''B''' coming towards the viewer perpindicular to the bar system.


			A) Calculate the amount of current '''I'''running through the resister.

			B) On a diagram, clearly show the surface charge distribution all the way around the circuit and the direction of the conventional current '''I'''.

			C) Calculate the constant speed '''v''' of the falling bar.

	In electromagnetics, a generator is a device that takes mechanical energy and converts it into electric energy. Thanks to Faraday's Laws of Motional EMF, it is possible to induce EMF in a conductor by moving it through a magnetic field. If that conductor is connected to a complete circut, the conductor will act like a battery and create an electric current in the circut.
