Is it possible to create a water heating system by electro motor which rotates the magnetic ring (variable magnetic field of certain frequency) through which the copper pipe (water inside) is going?

Yes and no.
Yes, the variable electric field would induce currents in the copper and the resistance of the copper would cause those currents to warm the copper, and thus the water.
No, there are many more efficient ways to turn electrical energy into hot water.
