When a magnetic field and a wire are moved near each other the voltage produced is said to be?

Induced.


The magnitude of the voltage induced in a conductor moving through a stationary magnetic 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.


Electromagnetic induction occurs when?

a conductor is moved through a magnetic field a conductor is moved through a magnetic field


When a conductor is moved in a magnetic field a voltage will be induced on the conductor however current won't flow through the conductor unless the conductor is what?

moving


How do magnets help generators produce electricity?

The effect used to generate electricity is that, if a wire is moved through a magnetic field, a voltage is generated.


Has the earth's magnetic field ever changed?

Yes. The field has moved and flipped.


Why does a generator work?

When a conductive loop is moved through a magnetic field, an electric current is produced in the wire loop. This is the basis of electrical generators.


What would happen if you moved a strand of copper wire (assume a closed circuit) through a magnetic field?

Moving a conductor through a magnetic field would induce a voltage into that conductor. Asuming you are moving the conductor perpendicular to the field, then the voltage would be equal to the product of the velocity of the conductor, the length within the magnetic field, and the flux density of the field. If the conductor formed a closed loop, then a current would circulate around the conductor. Remember, though, its the voltage that is being induced, NOT the current.


When a magnet is moved through a coil of copper wire what is produced in the wire?

Electricity. That is the basis for how a generator works. When a coil of wire passes though a magnetic field, or a magnetic field through a coil of wire, electricity is produced. Taken in reverse, if you apply electricity to a coil of wire, magnetism is produced, and that is the basis for how a motor works.


What happens when a wire is placed within a magnetic field?

Electric current is produced.Nothing until it is moved at right angles{90 degrees) to the magnetic field between it's poles. The faster it moves the larger the voltage measured between the ends of the wire.

How do you increase current produced in electromagnetic induction?

1. Increase the strength of the magnetic field. (More field lines to be cut by wire, therefore more voltage induced) 2. Move the magnet - or the wire - more quickly. (More field lines cut per second, therefore more voltage induced) 3. More coils in wire. (A single straight wire moved in a magnetic field will cut the lines once, but a coil of wire will cut the lines twice. More coils, more cutting, more induced voltage).


How change in magnetic field can induce electric current in conductor?

If there is a change in a magnetic field, a current can be induced into a conducting loop. The change can occur if the strength of the magnetic field is changed, or if the conductor is moved in and out of the field.


How can you generate electricity using magnets?

When a conductor is moved through a magnetic field ("cuts the field lines"), a voltage, and a current, is induced in the conductor. Thus, mechanical energy is converted tinto electrical energy.


What is the lateral speed of a conductor of 1 meter in length when it induces a voltage of 30 when moved at right angles across a magnetic field of 2 teslas?

Electromagnectic induction occurs when?

a conductor is moved through a magnetic field


When a conductor is moved through a magnetic field the force of the magnetic field generates what in the conductor?

A: a flow of current or electrons following the thumb rule.


What happens when a coil wire is moved across the lines of a magnetic field?

When coil is moved in a magnetic field in such a way that the magnetic flux linked with the coil gets changed then an emf i.e. electromotive force is induced in beween the ends of the coil


What is magnetic induction?

Electromagnetic induction is the process of inducing electric current in a coil with the help of a magnet.Whenever a conductor is moved through a magnetic field, or the magnetic field fluctuates in strength (as with an AC electromagnet), a current will be induced in that conductor. Induction cooktops work by passing a large AC current through a conductor under the cooktop, creating a fluctuating magnetic field which induces an electric current through the cookware - heating the cookware by electrical resistance.The process by which a substance, such as iron or steel, becomes magnetized by a magnetic field. The induced magnetism is produced by the force of the field radiating from the poles of a magnet.CommentFurther to the original answer, it is a voltage that is induced into a conductor, NOT a current.


What does a conductor do in a magnetic field when current is suddenly passed through it?

the conductor has to be moved.


Has earths magnetic field ever moved or changed?

Yes. The Earth's magnetic field changes and has flipped in historical times. Velikovsky noticed this in examining the magnetic oruientation of ancient pottery.


Why does moving the magnetic field past the wire induce a voltage?

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.


Can a current be generated by a magnetic field?

Yes. More specifically, a conductor must be moved in a magnetic field, or the magnetic field must move. (Otherwise, generating a current would violate Conservation of Energy, so without movement, no current is possible.)


When a coil of wire is moved across the lines of a magnetic field a current is induced in the wire?

yes
