(c) of time, and find the value at time t = 1.0 s. d = 1.0m and a = 2.0m. Derive an expression for the magnitude of the emf in the loop as a function 1.0 s and use (d) Lenz's law to argue which direction the induced current will flow (clockwise or counterclockwise). Find the magnitude of the induced current Itoop at time t (e) Explain by calculating the force between the wire and each segment of the loop. If there is a net force, will it be attractive or repulsive? Will the loop feel an overall force due to the presence of the current?

Typo, the distance is "b" instead of "a".
Expert Solution
Step 1
Given:
The wire's current decreases steadily at a rate of = 5.0A/s.
internal resistance =
square loop N=1
Note: As per I have given solution for the first 3 subparts please post others in next submission
Step 2
a)
Loop is in right of wire so the magnetic field will encounter inside loop page.
b)
Magnetic field due to infinite long wire
