Explanation:

MCB h miniature circuit breaker

hans Christian oersted discovered the magnetic effect of current

it works on the heating effect of current

it do not have filament

it verifies on the magnetic effect of current

Yes

it is not very strong when it is off, the magnetic effect Stops passing through it and it is temporary.

Yes since a current carrying wire was able to deflect a compass needle it was concluded that the electric current following in a wire gives rise to a magnetic field around it
