Question
Transcribed Image Text:**Problem Statement:**
In the figure, the magnetic flux through the loop increases according to the relation \( \Phi_B = 6.1t^2 + 7.1t \), where \( \Phi_B \) is in milliwebers and \( t \) is in seconds.
**Questions:**
(a) What is the magnitude of the emf induced in the loop when \( t = 1.8 \, \text{s} \)?
(b) Is the direction of the current through \( R \) to the right or left?
**Diagram Explanation:**
The diagram shows a loop with a resistor \( R \) at the bottom, surrounded by a magnetic field represented by green dots. The magnetic flux density is directed into the page. The loop is circular at the top and connects vertically to the resistor.
**Inputs for Answers:**
- For part (a), provide the numerical value of the induced emf and select the appropriate units.
- For part (b), choose the direction of the current through the resistor \( R \) by selecting either right or left from a dropdown menu.
