Energy is stored in inductor in magnetic field.magnetic field exists only where the charge is moving.so does the moving charge is stored in an inductor.if not then how is energy stored in inductor?
the energy is stored in the magnetic field surrounding the inductor, which takes time to build up and time to collapse. when current is first applied, the absence of magnetic field opposes it until the field has built up. when current is removed, the built up magnetic field opposes it forcing current to flow until the field has collapsed.nothing happens instantly when dealing with fields, either magnetic or electrostatic.
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.
Is it true that A magnetic field continues to exist around a wire that is no longer carrying an?
Yes, but only for a very brief period of time.
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.
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.
What earth field reverses from time to time?
magnetic field
What is Earth's field that reverses from time to time?
The Earth's Magnetic field.
What is earths field that reverses from time to time?
The Earth's Magnetic field.
How can the magnetic field of the Earth be sued to estimate the age of rocks found in the Earth?
By knowing the precise orientation of the rocks magnetic field, you can compare its magnetic field direction to the known direction of the magnetic field over time since the "north pole" wanders over time. The rock locked in its magnetic field when it cooled from magma.
What is induced by an electric field that changes with time?
A magnetic field
Why does the earths magnetic field change over time?
The Earth's magnetic field changes over time because that is the way that God makes it.
Can an electric field exist without a magnetic field?
An electric field can exist even without the presence of a magnetic field. An example of this is a stationary electric field.
What are the physical significance of Maxwell's equations?
As per my knowledge,Maxwell's equations describes the relations between changing electric and magnetic fields. That means time varying electric field can be produced by time varying magnetic field and time varying magnetic field can be produced by time varying electric field.
How magnet get their magnetic field?
They are all induced by some external magnetic field. Once upon a time this was always the earth's magnetic field ... (which is a dynamo effect - a spinning conductor) but these days is usually from an elector-magnet.
What do lava samples tell scientists about what has happened to the earth magnetic field over geologic time?
The magnetic field periodically changes its orientation.
How is an electromagnet wave generated?
We produce electric field and magnetic field. If we change the electric field with time (so magnetic field alse change), required frequency, then we produce electromagnetic wave.
How does earths magnetic field change over time?
It changes over time through direction and strength. So therefore Magnetic North becomes Magnetic South.
