A galvanometer is an electrical meter. by any kind of force

• coupled force

• friction

• gravity

• magnetic force

Why do we have to put a soft iron core in the middle?

• so that the angles are parallel throughoutr

• so that the angle is very valuable

• to make the coil at a perpendicular angle

• no right

Why does the pointer stick stand still?

• The coupling moment force is very high.

• Coupled moment force equals reverse torque.

• Inform the moment of force coupled with a small value.

• all correct
