Punjabi (Gurmukhi) has two symbols for indicating nasal sounds.
One of these, the dot (ਂ) is called bindi (ਬਿੰਦੀ/بندی) in Punjabi. Along with the other one, the tippi (ਟਿੱਪੀ/ٹپی ੰ ), it's a sign used for nasalization, for example, in a velar nasal (the 'n' sound in words ending in '-ing') or for a \m\ before certain consonants (-mb, -mp etc.).
As an illustration, 'big' written in Punjabi would be 'ਬਿਗ/بگ' but 'bing' is written as 'ਬਿੰਗ/بنگ'. Similarly, while 'log' is written as 'ਲੌਗ/لوگ', 'long' is written as 'ਲੌਂਗ/لونگ' with the bindi/tippi indicating that some air escapes through the nose during the production of the sound by the mouth.
One more thing! There are rules as to which vowel sign (ਮਾਤਰਾ/ماترا) employs what nasal symbol. Also note that these symbols are for Gurmukhi script, Shahmukhi script uses only one symbol 'noonguna' (ں) for nasalization.
Bindi: used with kanna (ਾ), bihari (ੀ), laan (ੇ), dulaavan (ੈ), hora (ੋ) and kanora (ੌ).
Tippi: used with mukta (no vowel), sihari (ਿ), aunkar (ੁ) and dulainkar (ੂ). The only exception is with aunkar and dulainkar when they are used with oora (ੳ) i.e. ਉ and ਊ use bindi and not tippi.
Let's look at all the cases one by one.
ਮਾਂ (mother)
ਸਾਂਝ (partnership/relationship)
ਮੀਂਹ (rain)
ਅਸੀਂ (we)
ਗੇਂਦ (ball)
ਸਕੇਂ (conditional form of the verb ' ਸਕਣਾ')
