A good question. When an electron is moved, it will generate a magnetic force.
In a permanent magnet, there are a 'magnetic domains' in which a number of electrons have similar spin direction. In an electromagnet, there are, by definition, a number of electrons moving in the same direction.
If you do not have a moving electron, you do not have a magnetic field! From this statement, you may deduce that the amazing magnetic loops on the Sun, are generated by currents flowing inside the Sun.
What else can I help you with?
Can moving electrons through a magnetic field can produce an electric current?
Yes, a moving electron in a magnetic field can induce an electric current. This is the principle behind electromagnetic induction, where a changing magnetic field induces an electric current in a conductor.
How can you induce a magnetic field in a piece of iron?
You can induce a magnetic field in a piece of iron by exposing it to a magnetic field, passing an electric current through it, or by rubbing it with a magnet.
Is the process of producing an electric current by moving a loop of wire through a magnetic field?
A current is induced in the conductor by the moving magnetic field (relative to the wire, the field is moving) I guess induction might be the term you are looking for.Another AnswerMoving a magnet through a loop of wire will induce a voltage, not a current, into a coil. If the coil forms a closed loop, then a current will result. But it's a voltage that's being induced, not a current -the current is merely the result of that voltage.
What can induce an electrical current in a wire?
An electrical current can be induced in a wire by a changing magnetic field passing through the conductor. This phenomenon is known as electromagnetic induction, and it is the basis for the operation of generators and transformers. Moving the wire through a magnetic field or changing the magnetic field around the wire can result in the generation of an electrical current.
Is it true that a magnetic field is surrounded by moving electric charges?
Yes, a changing magnetic field will induce an electric field, leading to the movement of electric charges. This phenomenon is described by Faraday's law of electromagnetic induction.
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.
What is induced by the rapid alternation of a magnetic field?
you would induce voltage therefore chanfing the magnetic field
Can a magnetic field induce voltage in another nearby conductor?
A: Believe it or not that what a transformer does
What are 3 things required to induce voltage?
A magnetic field, a conductor and movement.
Does a moving magnetic field produce an electric current?
Yes, a moving magnetic field can induce an electric current in a conductor, according to Faraday's law of electromagnetic induction. This phenomenon is the basis for many applications of electrical generators and transformers.
The magnitude of the voltage induced in a conductor moving through a stationary magnetic field depends on the what?
The magnitude of the voltage induced in a conductor moving through a stationary magnetic field depends on the length and the speed of the conductor.
Can moving electrons through a magnetic field can produce an electric current?
Yes, a moving electron in a magnetic field can induce an electric current. This is the principle behind electromagnetic induction, where a changing magnetic field induces an electric current in a conductor.
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.
Does an electric current produces a magnetic field?
yes*edit: don't confuse moving with changing. A change in magnetic field strength/direction will induce an electric current.
Why does a transformer require alternating current?
In order to induce voltage as an output, a changing magnetic field is needed. To create a changing magnetic field in the transformer a changing current and that is an alternating current.
How can you induce a magnetic field in a piece of iron?
You can induce a magnetic field in a piece of iron by exposing it to a magnetic field, passing an electric current through it, or by rubbing it with a magnet.
What does a rapid change of a magnetic field induce?
It does not have to be positive or negative either one will produce reversal of the voltage applied by a factor
