Present participle Vs past participle

Q.My sister was charmed with silk. She bought ten yards.

Ans. Being charmed with silk, my sister bought ten yards.

Deceived by his friends, he lost all hope.

^this is the example of past participle given in my book and the the former is a question from an exercise in my book.

I have a little confusion as to why passive present participle Being charmed with silk is used but not the past participle charmed with silk. I would also like to know when passive present participle is used and when past participle, because both seem to me to have very similar meaning.
