Daniiel said:So the by faradays law the change in the system will induce a current which opposes the change, so when you move the first ring closer, it will produce a current in the opposite direction to loop so that loop 2 is pushed back to its initial position.
And if loop 2 is moved away from loop 1 a current will be produced in the same direction as loop 1 so loop 2 is pull back towards loop 1.
I'm pretty sure that's right
have a look at the first and lasts posts

Electromagnetic induction is the process by which a changing magnetic field induces an electric current in a conductor. This phenomenon was discovered by Michael Faraday in the 1830s.
Electromagnetic induction works by moving a magnet or a conductor through a magnetic field, or by changing the strength of a magnetic field near a conductor. This creates a changing magnetic field, which in turn induces an electric current in the conductor.
In AC (alternating current) induction, the magnetic field and the induced current are constantly changing direction. In DC (direct current) induction, the magnetic field and the induced current are constant. AC induction is used in most household appliances, while DC induction is used in electronic devices.
Electromagnetic induction has many practical applications, including generators, motors, transformers, and induction cooktops. It is also used in wireless charging, metal detectors, and MRI machines.
One common problem with electromagnetic induction is eddy currents, which are currents induced in a conductor that can cause energy loss and heating. Another problem is electromagnetic interference, which can affect electronic devices and communication systems. These problems can be minimized through proper design and shielding.
