1.7 Electric Dipoles

Learning Objectives

By the end of this section, you will be able to:

  • Describe a permanent dipole
  • Describe an induced dipole
  • Define and calculate an electric dipole moment
  • Explain the physical meaning of the dipole moment


Reflect on this question and take notes on how you would answer it. Then we will share these thoughts together in a class discussion.

An electrically neutral dipole is placed in an external E-field.

(a) In which situation(s) is the net force on the dipole zero?

(b) In which situation(s) is the net torque on the dipole zero?
