Hi Arpita. No, not all the beagles bite. There are multiple reasons for unnecessary biting and it could be due to male dominance/fear/pain/insufficient training. I suggest you to get him clinically examined and neutered if not done. Training him again would be an another option. Discourage him and give treats whenever he tries to bite. Show positive reinforcement. But taking a help from a dog behaviourist would be a great option.
