What is produced when wire coils are spinning between two magnets?

Magnetic fields can be used to make electricity Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current. Electricity generators essentially convert kinetic energy (the energy of motion) into electrical energy.

How does the magnet affect the spinning of the coil?

EXPLANATION: When electricity is passed through a wire coil (as you are doing when you connect the coil to the battery), you create an electromagnetic field, which pushes the coil away from the magnet. When the circuit is complete again, the magnetic field once again repels the coil, so it keeps spinning.

What is the best way to generate an electrical current in a coil of wire?

The simplest generator consists of just a coil of wire and a bar magnet. When you push the magnet through the middle of the coil, an electric current is produced in the wire. The current flows in one direction as the magnet is pushed in, and in the other direction as the magnet is removed.

Why a coil of wire produces a stronger magnetic field than a straight wire?

The magnetic fields generated by the separate turns of wire all pass through the center of the coil and add (superpose) to produce a strong field there. The more turns of wire, the stronger the field produced.

Where is the strongest magnetic field in a coil?

As can be visualized with the magnetic field lines, the magnetic field is strongest inside the magnetic material. The strongest external magnetic fields are near the poles. A magnetic north pole will attract the south pole of another magnet, and repel a north pole.

What force makes the coil spin?

The permanent magnet attracts its opposite pole on the coil and repels its like pole, causing the coil to spin. Another way to describe the operation of the motor is to say that the permanent magnets exert forces on the electrical currents flowing through the loop of wire.

What causes coils to spin?

The coil of wire is mounted in the gap between the two magnets. The split rings make electrical contact with the coil and reverse the current every half turn. When an electric current flows through the coil, a force is exerted on the coil, causing it to spin.

How does a spinning generator make electricity?

In modern generators, the rotating elements are surrounded by a large magnet and coils of copper wire. The magnet is rotated as a result of the spinning wheels, and this results in a powerful stream of electrons, therefore converting the mechanical energy into electric energy.

Why does more coils increase the strength of an electromagnet?

The magnetic field around a solenoid is much stronger than a bar magnets because each coil acts like a magnet when a current is passed through it, when the coils are repeated several times it is like having several mini magnets in a row, making it more stronger than bar magnet.
