    Induced Voltage of a Magnetic Field passing through a loop

    I am pretty sure I did this correctly (I got the correct answer at least). I just want to ensure that my process was correct. I took the derivative of the magnetic field: dB/dt = (2.5t-.500)T when t = 2.00 and kept the area and the cosine of the angle constant since their rate of change is 0...

    Induced Voltage of a Magnetic Field passing through a loop

    Thank you! I will reference my notes and textbook and ponder about this a bit. I considered whether that was the appropriate angle to use but I suppose I haven't thought about it enough. I will report back after I redo this problem with the new information you have provided. Thank so much!

    Induced Voltage of a Magnetic Field passing through a loop

    I see what you mean. Yes I typed it incorrectly. \frac{dB}{dt} = (2.5t - .500) I had typed a + sign.

    Induced Voltage of a Magnetic Field passing through a loop

    Are you saying I need to find the angle measured relative to the plane of the loop as in 90-65 = 25?

    Induced Voltage of a Magnetic Field passing through a loop

    So it is correct to factor those out as constants and take the derivative of the magnetic field B? I think I made a typo when entering in latex but I will check my paper to see if I made the same error when I did it by hand. I will try this and see what I get. Thank you very much for such a...

    Induced Voltage of a Magnetic Field passing through a loop

    Homework Statement A magnetic field passes through a circular loop of radius 14 cm and makes an angle of 65° with respect to the plane of the loop. The magnitude of the field is given by the equation: B = (1.25t2 - .500t + 4.00)T. a) Determine the voltage induced in the loop when t = 2.00 s...

    I want to go back to school for Physics

    Taylor, my man. I am afraid that the field of astrophysics has absolutely nothing to do with religion from a scientific perspective. It is merely concerned with describing the physics of astronomical and celestial objects/mechanics/phenomena/etc. I am not sure that I understand what your goal is...

    Schools Will these Junior College Math Courses Be Sufficient?

    I am currently enrolled in community college with a transfer agreement to University of Virginia to double-major in pure maths and computer science. I have spoke with two of our advisors, however, neither of them could really understand what I was trying to major in so their advice was limited...

    Courses Which Courses Best Support a Neuroscience Major Focused on Research?

    The reason that I want to study suicide and depression is because December 21, 2008, I broke into my 19 year old brother's apartment, bedroom and then bathroom in an effort to save his life but I found him hanging on his bathroom door with a broken neck after I broke my way in. I took him off of...

    Courses Which Courses Best Support a Neuroscience Major Focused on Research?

    I have selected Neuroscience is the major that I will be pursuing (for personal and intellectual reasons). I work forty hours a week and take classes at night and online through my community college. I currently have a transfer contract with William and Mary, upon completion of the required...
