A circuit breaker is an automatic device for stopping the flow of current in an electric circuit as a safety measure.

A magnetosphere is the region surrounding the earth or another astronomical body in which its magnetic field is the predominant effective magnetic field.


Hope this helps!! All credit goes to Google though

Answer:

Circuit breaker is an electrical switch placed in a circuit which automatically switches off when there is excess current- overload, short circuit. A circuit breaker automatically breaks the circuit and protects it from damage.

The magnetosphere is the magnetic field of the Earth surrounding it and interacts with the solar wind. Its a region in space where magnetic field of the earth is dominant.
