A single loop of steel wire, lying flat in a plane, has an area of 7.80 cm² and a resistance of 1.80 2. A uniform magnetic field points perpendicular to the plane of the loop. The field initially has a magnitude of 0.500 T, and the magnitude increases linearly to 1.50 T in a time of 1.12 s. What is the induced current (in mA) in the loop of wire over this time? MA

A generator has a coil with 1260 turns that are each 0.020 m in diameter. The coil rotates at 3600 rpm in a 0.670 T magnetic field. If a 20.0 Ω resistive load is connected in parallel with the generator, what is the average power used by the load?   ____ W

Currents in dc transmission lines can be 100 A or higher. Some people are concerned that the electromagnetic fields from such lines near their homes could pose health dangers. For a line that has current 130 A and a height of 8.0 m above the ground, what magnetic field does the line produce at ground level? Express your answer in tes Express your answer in teslas. B = Submit Part B B BE = Submit What magnetic field does the line produce at ground level as a percent of the earth's magnetic field, which is 0.50 G. Express your answer as a percentage. ΓΕΙΑΣΦ Part C OO ΑΣΦ I Request Answer Request Answer Is this value of magnetic field cause for worry? ? T ? % No. Since this field does not differ a lot from the earth's magnetic field, it would be expected to have almost the same effect as the earth's field. Yes. Since this field does not differ a lot from the earth's magnetic field, it would be expected to have almost the same effect as the earth's field. No. Since this field is much…

a flat circular coil with 150 turns, a radius of 6.00 * 10^-2 m, and a resistance of 0.30 is exposed to an external magnetic feild that is directed perpendicular to the plane of the coil. the magnitude of the external magnetic feild is changing with time at a rate of 0.80 T/s.  a. find the magnitude of the induced current.  b. find the magnitude of the induced magnetic feild B(induced) at the center of the coil.
