Currently, it is not feasible to find out who removes or mutes others in Teams meeting.
As you know, attendees have no permission to remove or mute other participants. So, to prevent this situation, it recommends you make students as attendees in Teams meeting.
As michev said, log files to monitor participants activities during Teams meeting is not supported.
I found a feedback in Teams UserVoice about this feature. You could vote for it here:
Microsoft will always focus on customer’s feedback and experience. Some new features would be added to the services based on customers' feedback in the future, and your good ideas will be very helpful for them to improve the service.
Your time, understanding and cooperation will be highly appreciated.
