HEYA MATE

UR ANSWER IS GIVEN BELOW:-

1)when key is open no reading will be seen in galvanometer. when key is closed u will observe readings.

2)magnetic field would be observed in both coils

3)the phinominon is current carrying threw a coil and current will be seen on another coil.

5)coil 1and coil 2

HOPE IT HELPED MARK AS BRAINLIEST

^_^


Randomboy123: Lol name the two coils and u wrote coil 1 and coil 2?

A)

i) when key is closed deflection in galvanometer is observed in coil2.

ii) when key is opened then also deflection is observed in galvanometer connected to coil 2.

B)when current is passed continuously no deflection occurs in galvanometer.

C)the phenomenon responsible is electromagnetic induction.

When a coil and a magnet are moved wrt each other then a current is induced in the coil.

D) flemings right hand rule is used.

It says : stretch the thumb , forefinger and middle finger of ur right hand such that they are mutually perpendicular to each other. If thumb points in the direction of motion of magnet/coil and middle finger points in the direction of magnetic field then the forefinger will point in the direction of induced current.

R) two coils used are coil 1 and coil 2 .
