Last week Thursday on March 10 the earthquake hit Japan.  The earthquake created a tsunami that hit northeastern Japan and spread across the Pacific.  Like every other major earthquake that occurs on the ring of fire, this past one generated a tsunami.  Once my mom heard about the earthquake and tsunami warning, she made my family evacuate since we live across the street from the ocean.  We were pulling out of the driveway when my mom told me to go grab a flashlight in case power went out.  I hurried upstairs and found my shake flashlight which doesn't require batteries which I thought was good in case we run out of batteries.  The flashlight doesn't need batteries because it can generate its own electricity.  When shaken, a magnet passes through a coil. The changing magnetic field that is produced creates a changing flux.  The changing flux induces a voltage in the coil.  The voltage makes a current which consequentially makes power to work the flashlight.
