Question Regarding electric field

[harishjee.com]

In polar molecules, dipole moment exists even in the absence of an external electric field.

please tell me it is true or false

what is your definition of a dipole moment? does this defn include an external field as an variable? you may need a field to detect a presence of a moment but do u need it to define it in the first place? You need to think about these issues...

Why do magnetic moments arising due to spins of ferromagnetic materials, tend to align parallel to each other?

In polar molecules, dipole moment exists even in the absence of an external electric field.

Yes. That's why they're called polar molecules!

can u understand me about dipole moment with or without electric field.

can u understand me about dipole moment with or without electric field.

Yes. Did you understand my answer? A permanent dipole moment does not require an external electric field. Examples of highly polar molecules would be the alkali halides.
