What else can I help you with?
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.
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.
What does a changing magnetic field induce in a conductor?
A changing magnetic field induces an electric current in a conductor.
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.
Motion magnetism and a conductor will create what?
Motion between a magnet and a conductor will induce an electric current in the conductor, according to Faraday's law of electromagnetic induction. This phenomenon is the basis for generating electricity in generators and power plants.
Does a change in magnetic field induce an electric current?
Yes, a change in magnetic field can induce an electric current in a conductor, as described by Faraday's law of electromagnetic induction. When a magnetic field through a conductor changes over time, it creates an electromotive force, which leads to the generation of an electric current in the conductor.
How does a magnet create electricity?
A magnet can create electricity through electromagnetic induction. When a magnet moves near a conductor, such as a wire, it creates a changing magnetic field around the conductor. This changing magnetic field induces a current to flow in the wire, generating electricity.
What is induced by the rapid alternation of a magnetic field?
you would induce voltage therefore chanfing the magnetic field
