The electromagnet's coil is attached to a pointer. When a current is in the electromagnet's coil, a magnetic field is produced. This field interacts with the permanent magnet's field, causing the loops of wire and pointer to rotate.
The pointer on a meter moves in response to changes in the quantity that the meter is measuring. For example, in a water meter, the flow of water causes the pointer to move. In an electricity meter, the amount of electricity being used will cause the pointer to move.

True. An electromagnet is used in a galvanometer to create a magnetic field that interacts with the current-carrying coil and causes the needle to move.
The pointer on a thermostat moves when the room temperature changes. This change in temperature causes the thermostat's sensor to detect the difference and adjust the pointer accordingly to indicate the new temperature reading.
A galvanometer needle can be moved by the flow of electric current through its coil, the presence of a magnetic field, or mechanical disturbances like vibrations or shocks.
A galvanometer is a simple meter that detects the flow of current. A current flowing in a wire causes magnetism around the wire. This is called electromagnetism. Like poles of a magnet repel and opposites attract. The Galvanometer uses these principles in order to move a pointer across a scale.
Basically, the pointer moves due to measuring the direct current (flow of electric charge) through an electric circuit.

To move the pointer on a microscope, you can adjust the mechanical stage controls that move the slide horizontally and vertically. Simply turn the knobs in the desired direction to position the pointer over the area of interest on the specimen slide.
All you need to do is just press the arrow keys and the cursor will move in the direction of the arrow that has been pressed. If you press and hold the one of the Shift keys at the same time, then it will also select cells as the cursor moves.
