![A perspective diagram showing a rectangular loop tilted in space. The loop has side lengths labeled 0.20 m along its edges. A small arrow along one edge of the loop indicates current I. A dashed normal line extends perpendicularly from the center of the loop face. Three horizontal, parallel solid arrows pointing to the right represent a uniform magnetic field labeled B. An arc indicates an angle labeled 30° between the normal line and the horizontal magnetic field lines. No other labels, lines, text, or axes appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1787461129-hh3jh0.jpg)
