Answer:
Emf induced i equal to 329.4 volt
Explanation:
Note : Here i think we have to find emf induced in the coil
Number of turns in the coil N= 180
Sides of square d = 30 cm = 0.3 m
So area of the square
Magnetic field is changes from 0 to 1.22 T
Therefore
Time interval in changing the magnetic field dt = 0.06 sec
Induced emf is given by
The answer is true because A current carrying wire is surrounded by magnetic field
