Let the grammatical job choose the spelling
Pronunciation offers no clue. Look for a person, a main thing, money, or a rule.
Person, money, or main: principal

Rule or belief: principle

Fairness is a guiding principle of the policy.
Direct answer
What is the difference?
Use principal for a school leader, a leading participant, an original amount of money, or as an adjective meaning main. Use principle only for a standard, rule, doctrine, or fundamental truth. Because the words are homophones, listeners need sentence context and writers need the spelling distinction.
