The student pilot was practicing pattern work and while turning onto the base leg of the traffic pattern, inadvertently pulled the mixture knob instead of applying carburetor heat, resulting in a total loss of power. She attempted to restart the engine by pushing the mixture knob back in, however, the propeller had already stopped rotating and the engine did not restart. The student pilot elected to perform a forced landing to a field. During the approach to the field, she realized the airplane was too fast and decided to land in an adjacent field. During the landing, the right wing of the airplane struck a guy wire, which resulted in substantial damage to the airplane. The student pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
