Question

i) Will the galvanometer (G) show any defalcation when a constant current flows in coil A. (ii) Will the galvanometer show any deflection when current in coil A is changed with the help of rheostat? (iii) Will there be any change I n deflection if the current in the coil A is changed at a faster rate? Explain your observation in each case.

Answer 1

1 is yes because the current carrying solenoid shows deflection as the magnetic field is exerted by coil A which makes the deflect in the coilB
