Answer:

Explanation:

the increase energy stored in thw system is proportional to the decrease in kinetic energy

The increase in the energy stored in the system is proportional to the decrease in kinetic energy.

What is energy stored in the system ?

"The energy stored in the system means the sum of energies of both magnets when second magnet stop spin and stick with first magnet. It is clear that the rotational kinetic energy of second magnet decrease and becomes part of the system. Hence the increase in the energy stored in the system is proportional to the decrease in kinetic energy."

What is kinetic energy ?

"Kinetic energy is a form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy."
