Question is worded poorly. The personnel assigned to a Magistrates court pretty much mirrors the personnel of any court. The Magistrate themselves, the Court Clerk, and a Bailiff.

Court personnel have various roles, such as judges who preside over trials and hearings, lawyers who represent clients, court clerks who manage court documents and records, bailiffs who provide security in the courtroom, and stenographers who transcribe court proceedings.

Officers of the Court.ADDED: (in the US) There is no all-encompassing term that covers ALL those personnel with just one name or title. Only the judge and members of The Bar (practicing attorneys) are referred to as 'Officers of the Court.'The remainder of the courtroom personnel are collectively referred to as court "staff." Bailiffs are usually (but not always) Deputy Sheriffs (in state courts), or in federal courts, US Marshals. The court clerk is an employee of the Clerk Of The Court (an elective office) and the court stenographer can either be an employee of the court system or a private subcontractor. Jurors occupy a special position, and are always referred to as simply 'Jurors' or 'The Jury.'
