In the arrangement shown in the figure. The metallic ring 2 is suspended by a non-conducting thread. The metallic ring 1 is connected to a cell of emf e0 and a variable resistance R as shown in the figure. If the resistance R is quickly increased to 2R, the ring 2 is

Due to increase in R, The current through ring 1 will decrease. As a result magnetic flux linked with 2 due to the current in 1 will decrease and current will be induced in 2. by lenz's law direction of current in 2 will be such that ring 2 will be attracted by 1 so as to keep the flux linked with 2 unchanged.
