The flexible loop in the figure attached has a radius of 14 cm and is in a magnetic field of strength 0.14 T. The loop is grasped at points A and B and stretched until its area is nearly zero. If it takes 0.21 s to close the loop, what is the magnitude of the average induced emf (in mV) in it during this time? Answer in mV

Question

The flexible loop in the figure attached has a radius of 14 cm and is in a magnetic field of strength 0.14 T. The loop is grasped at points A and B and stretched until its area is nearly zero. If it takes 0.21 s to close the loop, what is the magnitude of the average induced emf (in mV) in it during this time?

 

Answer in mV

The image shows a diagram featuring a circular loop lying flat on the page. A uniform magnetic field, indicated by crosses, points perpendicularly into the page. At the top of the loop is a labeled point "A," while at the bottom of the loop is a labeled point "B." **Diagram Explanation:** - **Circular Loop:** Represents a conductive loop positioned in the plane of the page. - **Magnetic Field:** Represented by a series of "X" marks, indicating the direction of the field is into the page. - **Points A and B:** Specific points marked on the loop, with "A" at the top and "B" at the bottom, likely used to reference specific locations for analysis or calculation.

The diagram features a circle centered among a grid of green crosses. On the circle, there are two marked points labeled as A and B. These points are aligned vertically with A positioned at the top of the circle and B at the bottom. The green crosses are evenly spaced, suggesting a coordinate grid layout however, specific axis labels or numerical values are not provided. This setup may be used to illustrate concepts related to circles in a coordinate plane, such as identifying coordinates, understanding geometric properties, or exploring points of intersection.
