Answer:
E = 0.3225 Volts
Explanation:
Given:
N = 24 turns
magnetic field, B = 1 T
Diameter of the coil, d = 3.7 cm = 0.037 m
area, A = [tex]\frac{\pi d^2}{4}[/tex] = [tex]\frac{\pi (0.037)^2}{4}=0.00107\ m^2[/tex]
Time, t = 0.08 seconds
Now, The induced Emf (E) is given as;
E = -d(flux)/dt
now, the flux is given as:
Flux = NBA = 24 × 1 × 0.00107 = 0.0258 Wb
Now, E = -0.0258/0.08
or
E = 0.3225 Volts
The current is opposite to the flux, thus the direction of the current will be anti-clockwise
