6. Suppose the surface of your dining room table is a magnetic field with the north pole at the north edge and the
   south pole at the south edge. If an electron passes through this field from ceiling to floor, which way will the
   path of the electron bend?
   (a) west
   (b) east
   (c) north
   (d) south
   (e) toward the ceiling

• left hand rule:A rule in electricity for finding the direction of the force of a magnetic field on a negatively
  charged particle moving through the magnetic field at right angles. Point the fingers in the direction of the
  field and the thumb in the direction of the moving charge and the palm will indicate the direction of the force
  on the charge.


• right hand rule:A rule in electricity for finding the direction of the force of a magnetic field on a positively
  charged particle moving through the magnetic field at right angles. Point the fingers in the direction of the
  field and the thumb in the direction of the moving charge and the palm will indicate the direction of the force
  on the charge.


• tesla:The tesla (symbolT) is the SI derived unit of magnetic flux density, commonly denoted asB, (which is
  also known as “magnetic field”). One tesla is equal to oneampNewton·meter.
