Question

The figure shows a stationary conducting loop adjacent to a vertical current- carrying wire. For which of the following conditions will a clockwise induced current circulate in the stationary loop? Current-carrying wire Stationary conducting loop Clockwise induced current The current in the vertical wire flows downward and its value is decreasing. The current in the vertical wire flows downward and its value is constant. The current in the vertical wire flows upward and its value is increasing. The current in the vertical wire flows upward and its value is decreasing. The current in the vertical wire flows upward and its value is constant.

Answer 1

Answer: the current in the vertical wire flows upward and its value is decreasing.

Here in the loop current is induced in clockwise direction. So the area vector is also inward and the magnetic field made by wire if current will go upward also be formed inward. But if the current will decrease then Change in flux will be decreased and induced emf will be positive so the current is also positive that means clockwise direction only. It is completely depend on Lenz's law induced current will oppose the reason of its formation.
