How alternating voltage is generated in a coil of wire when it is rotated between the poles of a magnet?
Electical current.=============================Answer #2:When a coil moves in the vicinity of a magnet, a voltage between the endsof the coil is produced. If the coil happens to be part of a closed circuit, thenthere could be an electrical current.Answer #3When a coil moves through a changing magnetic field, a voltage is produced, and when a resistor is connected to the coil some current flows and power is produced in the resistor. This power comes from the mechanical power needed to push the coil through the magnetic field when it carries a current.

What is produced if the poles of atoms line up in the same direction?
domains
Are global winds are produced by the movement of air between the equator and the poles?
yes
What is a magnetic created when electric current flows through a coil of wire?
Nothing is ever created, however, Electricity is INDUCED. The process is interchangeable, so if you pass a current through the wire you have a magnetic field (electromagnetism)lol.-originalposter- When you pass a magnet through a coil of wire, you induce an electric current. Also, if you move the coil instead you get the same result.-norman
What lets the north pole and south pole of a solenoid be able to change poles?
The poles of the solenoid depend on the direction of the current through the coil. The current reverses if you just reverse the polarity of the voltage between the ends of the coil. Heck, if you energize the coil with AC, you can do that 120 times every second.
How can the polarity of an electromagnet be determined if the directions of current flow is known?
Current flow is from positive to negative. Use the left hand rule for finding the north and south poles. Grab the coil in your left hand, with your fingers wrapped around the coil in the direction of the current flow. Your thumb will then point toward the north pole of the coil. Reverse the positive - negative connections to the coil and the north - south poles will change ends. The left hand rule will still be in effect as the current will now be flowing in the reverse direction as it was in the first connection.

What happens if a direct current is put through a coil suspended between the poles of a magnet?
The coil will align itself with the magnetic field (poles) of the magnet.
How the direction of EMF depends on the direction of current?
Current flow is from positive to negative. Use the left hand rule for finding the north and south poles.
