Explanation:
Given that,
Cross-sectional area, A = 8 cm² = 0.0008 m²
The initial magnetic field,
The final magnetic field,
Time, t = 1 s
The resistance of the loop, R = 2 Ω
We need to find the induced current. Due to the change in the magnetic field, emf will include in the loop. The induced emf is given by :
Let I is the induced current. Using Ohm's law,
V = IR
So, the induced current in the loop is .

Hello, Here is your answer ..
- V = 4/3*pi*(d/2)^3. In mks, then cm-g-s units, ρ = m/V = (0.004/6.02214179E+23) / (4/3*pi*(1E-10/2)^3) = 12685.582 kg/m^3 = 12.685582 .
