Magnetic Energy formulas, units, and examples

[Clarkie]

1. My teacher has given me a poster board to do on magnetic energy even though she has explained nothing about the subject, nor is there anything in my book. I am looking for the formula for finding magnetic energy and examples from everyday life.

All I got was 1/2BH, but I have no idea what that stands for (the B and the H?). I am guessing the unit is joules as for all the other energies.
