What is induced by the rapid alternation of a magnetic field?
you would induce voltage therefore chanfing the magnetic field
What is the key when using a magnet and a conductor to induce current in a conductor?
Motion
Electricity running through a wire will induce field?
A magnetic field around the wire.
Why a double coil transformer does not work on a pure DC voltage source?
According to Faraday's Law only if there is change in flux linkage of a conductor then current is induced between mutual inductors. Now DC will induce a constant a constant flux in the transformer core, consequently in the secondary coil. So constant flux cannot induce a current in the secondary. SUBHRA JYOTI SAHA
Will a DC motor actually produce voltage if it is spun in reverse?
AnswerIt'll produce voltage if you spin it forwards, too. The only difference between a DC motor and a DC generator is what you use it for.A long time ago, cars had DC generators on them instead of AC alternators. When you replaced a generator, you had to "polarize" it so it would make electricity. You hooked it up to your battery and let it run, as a motor, for a few seconds. Don't try that with an alternator because you'll break it.If you're looking for a neat little elementary-school science project, you can use little Radio Shack electric motors as generators for things like windmills, water wheels, dynamos turned by bicycle tires...Actually, yesA motor works by passing current through the conductors of an electromagnet (the rotor or armature) suspended in the magnetic field of a permanent magnet (or another electromagnet). The rotor is the moving part, that is, the part that spins. If instead of energizing the rotor's windings, you turned the rotor by hand, you would indeed induce a current in the rotor's windings. Basically you have created a generator.Motors work on the basic principle of a current going through a conductor producing a magnetic field around the conductor. If you reverse that you have a magnetic field around a conductor which produces current.
What are 3 things required to induce voltage?
A magnetic field, a conductor and movement.
What do you create if you move a conductor through a magnetic field?
You would induce a voltage from one end of the conductor to the other.
What is the key using a magnet and a conductor to induce a current in the conductor?
A changing magnetic field, in the conductor, can induce a voltage (and, under the correct conditions, that in turn will result in a current). In the case of a permanent magnet, either the magnet or the conductor has to move.
How does a magnet create electricity?
It is not the magnet alone, but the movement of a conductor (wire) in a magnetic field will induce a voltage (and a current, if it is connected in a circuit).
The ability of conductor to induce voltage in itself when the current changes?
The ability of conductor to induce voltage in itself when the current changes is called inductive reactance.
The magnitude of the voltage induced in a conductor moving through a stationary magnet field depends on the?
The speed of the conductor through the magnetic field, which translates into the number of magnetic lines of force the conductor can cut per unit time, will determine the magnitude of the voltage induced in the conductor. As an additional factor, if a longer piece of wire can be moved through the magnetic field, it will induce more voltage as well. The more speed we can put on the conductor, and the more of the conductor we can move through the magnetic field, the more voltage we can induce in the conductor.
If a wire with no current passes a magnetic field of flux will voltage be induced into the wire?
Yes, for as long as the magnetic field is moving along the conductor. A static magnetic field will not induce current, a dynamic field is required.
Does the induced current depend on the resistance of the circuit?
In general, yes, it does. For example, if you move a conductor in a magnetic field, this will induce a certain voltage between the extremes of the conductor; the corresponding current will then depend on the resistance.

What is electromagnetic induction?
Electromagnetic Induction mainly deals with the ways that energy is shifted about between Electric and Magnetic fields in various circumstances. Here are some major examples:1. A moving Electric Current Induces a Magnetic field: Electromagnets.2. A moving conductor in a magnetic field Induces an Electric Current: The Dynamo or Electric generator.3. An Electrified Conductor in a Magnetic field Induces motion in the Conductor: The Electric Motor.Related Information:Albert Einstein's considerations of inductance, an Electrified length of conductor moving through a Magnetic Field in an empty volume of space, led him to his theory of Special Relativity.
Could an induction type instrument be used to measure a pulsing DC signal of varying voltage?
Yes. As the DC is pulsed or varied in voltage, it will induce a varying magnetic field which can be detected with another inductor.
How does electromagnetic induction produce induced current?
Before you can understand how electrical energy is supplied by your electric company, you need to know how it is produced. A magnet and a conductor, such as a wire, can be used to induce a current in the conductor. The key is motion. An electric current is induced in a conductor when the conductor moves through a magnetic field. Generating an electric current from the motion of a conductor through a magnetic field is called electromagnetic induction. Current that is generated in this way is called induced current. To induce a current in a conductor, either the conductor can move through the magnetic field or the magnet itself can move.
