Magnetic field flux lines around the conductor w/ current are circular.

  Field into page
Field out of page


To find the direction of the flux lines: 

 

a) Use north pole of a compass

 

b) "First Left Hand Rule" Why Left and not right??

 

1) Palms away, left hand thumb direction of electron flow (current)

2) fingers curl in direction of magnetic field
