What is the orientation of a magnetic field?
By convention, magnetic field lines of force point to the “north” magnetic direction. With a circular field orientation like this, “north” is simply one direction about the wire, and “south” will be the opposite direction.
When the movement of the magnet is toward or away from the loop What happens to the current as read in the galvanometer?
If the magnet is moved, the galvanometer needle will deflect, showing that current is flowing through the coil. When the magnet is moved one way (say, into the coil), the needle deflects one way; when the magnet is moved the other way (say, out of the coil), the needle deflects the other way.
What happens as you move the north side of the magnet into the coil?
By using Lenz's Law. When we induce a current in the coil, it becomes an electromagnet. ... When the north pole of our magnet is moving towards the left hand end of the coil, the induced current flows anticlockwise (as we look at the left hand end). This makes the left hand end of the coil into a north pole.
In what direction is the magnet moving?
Just as for electric charges, opposite magnetic poles repel and like poles attract. Thus the magnetic field pointing from north to south points in the direction of the force on a NORTH POLE of a magnet.
