I'm stuck with Lenz's law, and questions involcing magnet/electromagnet theory
such as:
The diagram shows a bar magnet falling through an aluminum pipe. Electric currents are induced in the pipe immediately above and below the falling magnet. In which direction do these currents flow?

Any help/explanations would be greatly appreciated.
Thanks
