How Is EMF Induced in a Rotating Rectangular Loop?

AI Thread Summary
The discussion focuses on calculating the induced electromotive force (emf) in a rectangular loop rotating in a magnetic field. The loop has an area of 0.15 m² and is subjected to a magnetic field of 0.16 T, with the angle between the field and the loop's normal increasing at 0.70 rad/s. The initial calculation of magnetic flux yielded 0.024 Wb, but the user initially misread the area, leading to an incorrect emf calculation. After correcting the area, the user realized the mistake and acknowledged that the problem was straightforward. The final induced emf calculation reflects the corrected area and approach.

[SOLVED] Emf in a rectangular loop

Homework Statement


A rectangular loop (area = 0.15 m^2) turns in a uniform magnetic field, B = 0.16 T. When the angle between the field and the normal to the plane of the loop is pi/2 rad and increasing at 0.70 rad/s, what emf is induced in the loop?


Homework Equations


Flux=B*A

EMF=-N (delta flux/delta time)


The Attempt at a Solution



Flux= 0.16T * 0.15 m^2 = 0.024

Not sure what to do for the EMF.
Divided pi/2 radians by 0.70 rad/s to find time of 2.24 seconds. Then divided the flux by the time so... 0.024/2.24=0.011V

Thanks in advance for your help!

Actually, I was making a silly mistake...answer was off by one decimal place because I misread the area to be 0.015 m^2. Pretty simple problem lol

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
Thread 'Trying to understand the logic behind adding vectors with an angle between them'
My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
Thread 'Voltmeter readings for this circuit with switches'
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...
