What else can I help you with?
If your car moves over a wide closed loop of wire embedded in a road urface is the magnetic field on the earth within the loop?
yes the perpendicular component of earths magnetic field passes through the loop even if the car is moving above it or not , but no current is induced in the loop since it is not moving
What is produced when a magnetic field moves relative to a closed wire loop?
Faraday says you will induce a current in the wire.
What is the principle of a dc generator action?
A DC generator operates on the principle of electromagnetic induction, where mechanical energy is converted into electrical energy. When a conductor, such as a coil of wire, moves through a magnetic field, an electromotive force (EMF) is induced in the conductor according to Faraday's law of induction. This induced EMF generates direct current (DC) as the coil rotates within the magnetic field, typically created by permanent magnets or electromagnets. The direction of the induced current is determined by the orientation of the magnetic field and the motion of the conductor.
What happens when a wire moves through a magnetic field?
wire will move - there is a force acting on it. it's direction depends upon the orientation of current and magnetic field - a nice way to see this is by looking op a Google picture of Fleming's left hand rule. the force depends upon the strength of magnetic field, current and length of conductor (perpendicular to field) in the magnetic field.
Does a speaker have a motor or a generator?
A speaker functions as a motor rather than a generator. When an audio signal is applied, the speaker's voice coil moves within a magnetic field, converting electrical energy into mechanical energy to produce sound. In contrast, a generator converts mechanical energy into electrical energy, which is not the primary function of a speaker.
Would a neutron be deflected by a maagnetic field why or why not?
Yes, a neutron can be deflected by a magnetic field because it is a charged particle. The movement of the neutron will be influenced by the Lorentz force, which occurs when a charged particle moves through a magnetic field.
How is A charged particle moving in a magnetic field experiences a deflecting force that is maximum when the charge moves?
The deflecting force on a charged particle moving in a magnetic field is maximum when the charge moves perpendicular to the magnetic field lines. This occurs because the magnetic force acting on the charge is proportional to the velocity of the charge and the strength of the magnetic field, reaching its maximum when the angle between the velocity and the magnetic field is 90 degrees.
How is a current induced in a wire when a coil of wire moves through a magnetic field?
When a coil of wire moves through a magnetic field, the changing magnetic field induces a current in the wire through electromagnetic induction.
How induced current produce?
when a conductor moves accross a magnetic field or when magnetic field moves with respect to a stationary conductor for current to be induced, there must be relative motion between the coil and the magnetic.
How induced current is produce?
when a conductor moves accross a magnetic field or when magnetic field moves with respect to a stationary conductor for current to be induced, there must be relative motion between the coil and the magnetic.
When does magnetic force occur?
Magnetic force occurs when an electric charge is in motion. When a charged particle moves through a magnetic field, it experiences a magnetic force that can cause it to change direction. This force is the basis for the operation of devices such as electric motors and generators.
How does a conducting loop move through a constant magnetic field affect the generation of electric current within the loop?
When a conducting loop moves through a constant magnetic field, it induces an electric current within the loop. This is due to the phenomenon of electromagnetic induction, where the changing magnetic field creates an electric field that drives the flow of electrons in the loop, generating an electric current.
What happens when 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 is energy stored in a magnetic field?
Energy is stored in a magnetic field through the alignment of magnetic particles, creating a magnetic field that contains potential energy. This energy can be released when the magnetic field changes, such as when a magnet moves or when an electric current flows through a coil.
What is made of liquid iron and nickel moves to produce earths magnetic field?
The Outer Core has magnetic field and it is made out of iron and nickel
When a charge moves in the same direction as the magnetic field lines the magnetic force is?
Perpendicular to both the current and the magnetic field.
What happens when a wire 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.
