Asquare coil, enclosing an area with sides 3.2 cm long, is wrapped with 2,720 turns of wire. a uniform magnetic field perpendicular to its plane is turned on and increases to 0.45 t during an interval of 1.7 s. what average voltage (in v) is induced in the coil? express the answer with two decimal places.

Answer

Explanation:

given,                          

Side of square coil = 3.2 cm            

Number of turns = 2720                  

magnetic field in the coil increases to = 0.45 T

time interval = 1.7 s                  

average induced voltage in the coil = ?

length = 0.032 m                      

Area = 0.032² = 0.001024 m²

induced voltage                  

The average voltage induced in the coil is equal to                                              

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
