Cant rotate my character

Scripting
1

I am new to unity and am currently trying to make my character rotate using a Rigidbody. this is the code that Im using to rotate it

rigidBody.MoveRotation(Quaternion.AngleAxis(90, Vector3.up));

this piece of code is inside the Update() Loop and inside the Start() block is where I define rigidBody like so

rigidBody = GetComponent();

and the variable is created outside of the Start loop as a private variable.

I cant seem to get this to work I am getting no errors and the model is not rotating it just sits there any help is appreciated
