The graph below shows how the induced emf varies with the inverse of time. E 9.1 9.2 (V) 3 2 1 0 1 2 3 1 At State Faraday's law in words. Use the information in the graph to calculate the change in magnetic flux. (2) ​

Answer 1

Answer: The magnitude of the change is 27.6 Vs.

Step-by-step explanation:

To calculate the change in magnetic flux, we can use the formula:

emf = -dΦ/dt

where emf is the induced emf, Φ is the magnetic flux through the coil, and t is time.

we can see that the induced emf is 0 V when the inverse of time is 0. We can also see that the maximum induced emf is 9.2 V when the inverse of time is 1. Therefore, the change in emf is:

Δemf = 9.2 V - 0 V = 9.2 V

To convert this to the change in magnetic flux, we need to rearrange the formula:

dΦ = -emf/dt

The time interval between the two points on the graph is 1/3 s (since the inverse of time is 1 at the vertical line). Therefore:

dΦ = -(9.2 V)/(1/3 s) = -27.6 Vs

Since the change in magnetic flux is negative, this means that the flux is decreasing. The magnitude of the change is 27.6 Vs.

is this correct??
