Suppose that you wish to construct a simple AC generator with an output of 12 V maximum when rotated at 60 Hz. A magnetic field of 0.050 T is available. If the area of the rotating coil is 100 cm2, how many turns are needed?

N = 63.6

Explanation:

The emf induced in AC generator is given as follows:

for maximum output,

where,

V = Maximum Output Voltage = 12 V

N = No. of Turns = ?

f = frequency = 60 Hz

A = Area of Coil = 100 cm² = 0.01 m²

B = Strength of Magnetic Field = 0.05 T

Therefore,

N = 63.6

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.
