A circular metal ring is situated above a long straight wire, as shown in the figure. The straight wire has a current flowing to the right, and the current is increasing in time at a constant rate. Which statement is true?a. There is no induced current in the wirering.
b. There is an induced current in the wire ring, directed in clockwise orientation.
c. There is an induced current in the wire ring, directed in a counterclockwise orientation

The answer is: b. There is an induced current in the wire ring, directed in clockwise orientation

Explanation:

The direction of the magnetic flux can be calculated using the right-hand rule. As the current increases, the outward flow through the ring also increases, allowing the induced current to move through the ring, this is in accordance with Faraday's laws.

If we analyze Lenz's law, the current that is induced in the ring would move in one direction to reduce the outward magnetic flux. This flux can be decreased if the ring produces a magnetic field that moves into the ring.

If the right-hand ruler to the ring is used, the flow would move inward, and the fingers would curl around the ring clockwise. As a conclusion we can say that the current that is induced in the ring would move clockwise.

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.
