Monday homework problem 10.6 a simple generator is constructed by rotating a flat coil in a uniform magnetic field. suppose we rotate a flat coil of radius 2.0cm and 400 turns in the earth’s magnetic field 6 times per second so that the surface normal to the coil is parallel to the field once per revolution. the earth’s magnetic field is still about 4 × 10−5t. what is the maximum emf that would be measured acro

Our values are,

Number of rotations per second = 6

We begin calculating the cross-section Area, which is given by,

We can calculate the angular speed through the number of rotations per second,

With this velocity we can now calculate the maximum emf,

c

explanation:

i had this question and the answer was 3.15 miles.
