What is the Magnitude of the Magnetic Field in a Moving Loop?

AI Thread Summary
To find the magnitude of the magnetic field in the moving loop scenario, the change in magnetic flux is given as 0.0044 Wb over a time of 1.5 seconds. The equation E = delta flux / delta time is relevant for calculating the induced electromotive force (EMF). The velocity of the loop, 0.042 m/s, is crucial for determining how the area of the loop interacting with the magnetic field changes over time. The discussion emphasizes understanding whether the magnetic field strength, area, or both are changing to accurately apply the flux equation. Clarifying these variables is essential for solving the problem effectively.

Homework Statement



A rectangular loop of wire is moving toward the bottom of the page with a speed of .042 m/s. The loop is leaving a region in which a magnetic field is directed into the page; the magnetic field outside this region is zero. If during the time of 1.5 s the magnitude of the change in magnetic flux is .0044 Wb, what is the magnitude of the magnetic field?

Homework Equations



E = delta flux / delta time ?

The Attempt at a Solution


I thought this was the equation to use mainly. but i have no idea where the veloicty comes into play. any help would be appreciated!

Flux is B*A in this case, and you know d/dt (flux) = .0044. So you need to discover what part of the flux is changing: B, A, both?

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
