What happens when a coil of wire cuts through a magnetic field?

∙ 12y ago
If the magnetic field is fluctuating, or the coil of wire and magnetic field are moving with respect to each other, then a current is induced in the coil of wire.
If the two are stationary and the magnetic field is stable, then no current is induced in the coil. However, if there is a current in the coil, from another source, then the coil and the field will exhibit a relative force that will tend to move the coil with respect to the field.

the magnet momentarily absorbs the voltage and then releases the voltage many times per sec. creating a pulsating voltage

Working principle of ammeter?
An ammeter consists of a coil with very low resistance. when electric current flows through the coil, the coil induces a magnetic field which turns the needle.
When a electro magnet flows through a coil of wire wrapped around a bar of iron it makes what?
a magnetic field
What four factors determine how much voltage is induced by a magnet?
1. The amount of current flowing through the coil 2. The number of coil turns around the core 3. The rate at which the conductor moves through the magnetic field 4. The amount of reluctance that exists inside the magnetic field
What happens when the current in the coil is halved?
What happens when the current in the coil is halved? No pins are attracted. ... A magnetic field is always created around a wire when it carries electric current.
What are the three ways in which voltage can be induced in a wire?
Voltage can never be induced in a straight open wire because flux through a wire is zero but a coil made up of a wire can have induced voltage. Methods Move a magnet to and fro through the coil, the magnitude can be changed by altering the relative velocities between them Move the coil relative to he still magnet Place the coil in a time varying magnetic field such that the flux linked through the coil changes with respect to time Place the coil tn an uniform magnetic field and alter its area with respect to time
What happens when a electric current is passed through a coil of wires?
You generate a (stronger) magnetic field.
What happens when electric current passes through a coil of wire?
A magnetic field generates around the wire.
What happens if a direct current is put through a coil suspended between the poles of a magnet?
The coil will align itself with the magnetic field (poles) of the magnet.
What happens insider generator?
A coil of wire spins in a magnetic field
What describes the production of an electric current by moving a loop of wire through a magnetic field or moving a magnet through a wire loop?
moving a loop of wire through a magnetic Field. The rotation of a coil of copper wire trough a magnetic field changes magnetic field as "seen" from the coil inducing an alternating current.
What happens when you coil a permanent magnet with a wire and run current through it does the magnetic field increase?
The magnet super-amplifies the EMF field, and possibly has amperage running through the poles.
Once a current flows through the coil does it become a magnet?
ANY flowing current is surrounded by a magnetic field. The coil simply makes the magnetic field stronger.
What does a coil do?
Produce a magnetic field as electric current passes through it.
When an electric current is passed through a coil what does this create?
A magnetic field.
What is the role of the soft iron core?
In a moving coil galvanometer, soft iron core intensifies the magnetic field through it. this causes maximum number of magnetic field lines to pass through the coil.
Applying electrical current through a coil of wire creates a?
Magnetic field.
How can a change in voltage in a coil of wire be transferred to a neighboring coil of wire without physical contact?
When electric current flows through a coil of wire it generates a magnetic field. Variable current generates variable magnetic field. When a second coil is placed in a variable magnetic field of the first one an electric current is generated in it. Magnetic nature of the connection between two coils can be proved by the fact that it takes place only when the second coil is aligned with the magnetic field of the first one. Magnetic field of a coil can be traced with a compass.
