In a physics laboratory experiment, a coil with 250 turns enclosing an area of 11.8cm2 is rotated in a time interval of 3.00
Solutions
Expert Solution
Given
magnitude of magnetic field B = 7*10^ -5 T
area of the coil A = 11.8 cm^2
number of turns of the coil N = 250
magnetic flux through the coil
? = B A N cos?
initially the plane of the coil is perpendicular to the earth magnetic field
? = 0
total magnetic flux through the coil after it is rotated
? = BAN cos 0
= 7*10^ -5 * 11.8 *10^ -4 * 250
= 2.06*10^ -5 Wb
average induced emf in the coil
? = d ? /d t
= 2.06*10^ -5 Wb / / 3*10^ -2
= 0.687*10^ -3 V
