Your question is confusing, as you do not explain what you mean by 'isolate'. If you mean 'allow the core to retain some magnetism', then this will always be the case when the current through the coil is reduced to zero. In order to remove this 'residual magnetism', you will need to reverse the direction of current through the coil. This is a feature of what is known as 'hysteresis', by which changes in the flux density of a core 'lags behind' changes to the magnetic field strength that creates it.
To interrupt the current requires a more-expensive circuit-breaker. An isolator is used to isolate a section of power line after the current has been stopped.
Current transformers (CTs) are used to monitor the current (or lack of) in high-voltage systems, and their secondary outputs controls the behaviour of protection-system relays. The CTs (1) reduce the current to values that match the current ratings of the protective relays, and (2) electrically-isolate the relays from the high-voltage system.
There is no disadvantage with a current transformer -it does exactly what it's supposed to do, that is:reduce the current flowing in the primary circuit to a value that can be handled by its burden (ammeter or protective relay).electrically-isolate its secondary circuit from the primary circuit.
To isolate a patient from getting connected to stray voltages. An isolation transformer is used and batteries power it to further isolate you from the real world. Also for sensitive measurements to eliminate some of the noise and current loops.
So, the main purpose of an insulator is to isolate the current from being ground anywhere before the circuit completion. These insulators are essential for safety and they prevent direct contact from live wires.
An insulator is used to isolate current carrying components from conductive non current carrying components.

Circuit breakers can be of these types Fuse wire that melts when subjected to an over current. Magnetic. These contain a small electromagnet coil which becomes magnetised when a current flows through it. An over current operates a switch off mechanism which cannot be reset until the fault current is removed. Thermal, These contain a bimetallic strip that is heated by the fault current. The strip bends by uneven expansion of the two metals and operates a switch mechanism. Residual Current Device These monitor the current flowing to and from an electrical product. Any difference in current by a fault flowing via the earth protection wire will operated an electronic trip mechanism to isolate the device. Some breakers combine two of the above types eg thermal magnetic
Protection of busbars is mainly done using differential relays. These relays sense current flowing into the bus and current flowing out of the bus. If current in != current flowing out, the relay assumes there is a fault on the bus and trips breakers to isolate the bus.
isolate is a Verb... It is an action.
No. Though geographically surrounded by Indo-European Romance languages, Basque is classified as a language isolate. It is the last remaining descendant of the pre-Indo-European languages of Western Europe

Yes it is possible to isolate DNA from bone.

A flood could possibly isolate a township if it does a lot of damage to the area. It can also isolate a township if the roads into the town are no longer passable.
it can help isolate the area because their are volcanoes and its hot
