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 galvanometer is oriented so that the plane of the coil is vertical and aligned along parallel to the horizontal component He of the Earth's magnetic field (i.e. parallel to the local "magnetic meridian"). When an electrical current flow through the galvanometer coil, a second magnetic field H is created. At the center of the coil, where the compass needle is located, the coil's field is perpendicular to the plane of the coil. These two perpendicular magnetic fields add vertically, and the compass needle points along the direction of their resultant He + H. The current in the coil causes the compass needle to rotate by an angle\ \theta.
Work is done when force causes an object to move and capacity of doing work is called energy So, energy is required and consumed when force causes an object to move
The force that causes circular motion is called "centripetal force".
solid or a liquid
centrifugal force
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.

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.

Move the mouse pointer to rest on the item of choice
if you mean the loops that allow you to move stuff then your can get them at pretty much any magic store. if your looking online, then magicgeek.com is the BEST website for magic, they have everything, loops is a great trick by the way.
