= 0.55 T. If the displacement occurs in 0.25 s and the area of the coil is perpendicular to the magnetic field lines, what is the resulting average emf induced in the coil? -0.63V 3) A coil of 325 turns and an area of 19.5 × 10 −4 m 2 is removed from a uniform magnetic field at an angle of 45° in 1.25 s. If the induced emf is 15 mV, what is the magnetic field’s strength? 0.042T 4) A student attempts to make a simple generator by passing a single loop of wire between the poles of a horseshoe magnet with a 2.5 × 10 −2 T field. The area of the loop is 7.54 × 10 −3 m 2 and is moved perpendicular to the magnetic field lines. In what time interval will the student have to move the loop out of the magnetic field in order to induce an emf of 1.5 V? 1.26x10 -4 s 5) A rectangular coil 0.055 m by 0.085 m is positioned so that its cross-sectional area is perpendicular to the direction of a magnetic field, B . If the coil has 75 turns and a total resistance of 8.7 Ω and the field decreases at a rate of 3.0 T/s, what is the magnitude of the induced current in the coil? 0.12A

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
