    Calculating Number of Loops in Coil 2

    i got 202.67 for the change in flux of the first coil and .01865 for N of the second coil. that doesn't seem like it is right. is it?

    Calculating Number of Loops in Coil 2

    Homework Statement In each of two coils the rate of change of the magnetic flux in a single loop is the same. The emf induced in coil 1, which has 200 loops, is 2.67 V. The emf induced in coil 2 is 3.78 V. How many loops does coil 2 have? Homework Equations E=-N(delta Phi/delta t)...

    Solve Emf & Current for Changing Magnetic Field in Square Coil

    Homework Statement A magnetic field is perpendicular to the plane of a single-turn circular coil. The magnitude of the field is changing, so that an emf of 0.76 V and a current of 3.1 A are induced in the coil. The wire is the re-formed into a single-turn square coil, which is used in the same...

    How Much Current Flows in the Circular Loop When the Net Magnetic Field Is Zero?

    Homework Statement A very long, straight wire carries a current of 0.75 A. This wire is tangent to a single-turn, circular wire loop that also carries a current. The directions of the currents are such that the net magnetic field at the center of the loop is zero. Both wires are insulated...

    Determining magnetic field around two parallel wires

    Two long, straight wires are separated by 0.12 m. The wires carry currents of 3.5 A in opposite directions, as the drawing indicates. (a) Find the magnitude of the net magnetic field at the point A. (b) Find the magnitude of the net magnetic field at the point B...

    Calculating the Radius of a Rotating Coil in a Magnetic Field

    Two coils have the same number of circular turns and carry the same current. Each rotates in a magnetic field in a setup similar to the square coil in the figure below. Coil 1 has a radius of 5.5 cm and rotates in a 0.17 T field. Coil 2 rotates in a 0.42 T field. Each coil experiences the same...
