Electric Dipoles

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

Discuss!
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?
