If a circular loop of wire of radius 19.7 cm is located in a region where the spatially uniform magnetic field perpendicular to
the plane of the loop is changing at a rate of +2.0 ✕ 10−3 T/s, find the value of the induced EMF in this loop due to this changing magnetic field.
1 answer:
Answer:
Magnitude of induced emf will be 
Explanation:
We have given radius of the circular loop r = 19.7 cm = 0.197 m
So area of the circular loop 
It is given that magnetic field is changing as 
Emf induced in the circular loop is equal to 
So emf induced will be equal to 
So magnitude of induced emf will be
