Hey there,
Electric cells we use usually carry limited voltage. Here's an example: 1.5V. Really, there is no chance of any shot circuit. that's why MCB and fuse wires are not used in their circuit
.

Answer:
0.212V
Explanation:
The induced emf in circular loop is
N = Number of loops = 15
A = Cross sectional Area = 
= 0.0009
dB = change in magnetic Field = 0-0.5 = -0.5
dt = time taken = 0.1sec
= 0.212V
It's called covelant bonding
They are the standard system used by scientists worldwide, and
officially by almost all nations of the world. So if you describe a
measurement in terms of SI units, there's less chance that you'll
need to explain the measurement to anyone who reads it ...
most scientists and common people worldwide will understand
what your number means.
