SUMMARY
When the current in the first solenoid, which has a magnetic field of 1.5 T and a cross-sectional area of 0.30 m², is uniformly reduced to zero over 0.5 seconds, it induces a voltage in the second solenoid wound around it. Applying Faraday's law, the induced voltage can be calculated using the formula V = dΦ/dt, where Φ represents the magnetic flux. With the induced voltage determined, Ohm's law can be utilized to find the current flowing in the second solenoid, which has 150 turns and a resistance of 20 ohms.
