When the magnetic flux (field) intersecting a loop of wire changes, a voltage is induced between the ends of the loop. If a resistor is connected between the ends, a current flows and power is produced, but in this case a force is needed to move the magnet, and this provides the power.
What else can I help you with?
If you stopped the magnet midway through the loop what would happen?
The magnetic field generated by the magnet would also stop, causing the induced current in the loop to cease. This would result in a decrease in electromagnetic induction and the loop would have no current running through it.
What does the combination of a magnetic field and a coiled wire create strong magnet week magnet or neutral magnet?
it creates a very strong magnet A+ users
How do magnetic keepers work?
Magnetic keepers are used to preserve the strength of a magnet by providing a closed loop for the magnetic field to flow through. By placing a magnetic keeper across the poles of a magnet, it helps maintain the alignment of magnetic domains within the magnet, preventing them from becoming randomized and losing their magnetism over time.
What is the entire series of events through a three-neuron loop?
In a three-neuron loop, the first neuron sends a signal to the second neuron via a synapse. The second neuron processes the signal and sends it to the third neuron through another synapse. Finally, the third neuron integrates the signal and produces a response or transmits it further in the neural network.
Do magnetic field line complete loops?
Yes, magnetic field lines form closed loops that are continuous. They always start from the north pole of a magnet, loop around the magnet, and return to the south pole.
Process of producing an electric current in a loop of wire by either moving a magnet through the loop or moving the loop through the magnet?
This process is known as electromagnetic induction. When a magnet moves through a loop of wire or when the loop moves through a magnetic field, it induces a current in the wire due to the changing magnetic field. This phenomenon is described by Faraday's law of electromagnetic induction.
If you stopped the magnet midway through the loop what would happen?
The magnetic field generated by the magnet would also stop, causing the induced current in the loop to cease. This would result in a decrease in electromagnetic induction and the loop would have no current running through it.
A magnet inside a wire loop can produce a current?
Only while the magnet is entering or leaving the loop. If you hold it still, no current is generated. The same goes for a longer magnet where the loop is being moved, but the magnet always remains inside the loop; no current.
Electromagnetic Induction states that moving a magnet through a loop of wire creates what?
Moving a magnet through a loop of wire creates an electric current in the wire. This phenomenon is known as electromagnetic induction, discovered by Michael Faraday in the 19th century. It forms the basis for the working of generators and transformers.
What does the combination of a magnetic field and a coiled wire create strong magnet week magnet or neutral magnet?
it creates a very strong magnet A+ users
How to make magnetic power?
A note about terminology - magnetic energy is the energy stored in a magnetic field. I have never heard of magnetic power. However, I assume you are asking how to get electrical power from magnetic phenomena. The way this works is directly from maxwell's equations. Faraday's law says that the rate of change of flux through a loop (field through loop times area of loop) is proportional to the electric field around that loop, which is proportional to the current, if the loop is a conductor. The generator works by spinning a permanent magnet near a loop of wire. As the magnet spins, it induces current in the loop of wire, which can then be made to do useful work. A note about energy conservation: when the current in the loop is induced, it is always in such a way as to attract the spinning magnet, so the external agent has to do work to resist this.
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.
Moving a magnet quickly in and out of a coil of wire produces what?
Moving a magnet quickly in and out of a coil of wire induces an electric current in the wire due to electromagnetic induction. The changing magnetic field created by the moving magnet induces a current flow in the wire loop according to Faraday's law of electromagnetic induction.
Why loop produces in sonometer experiment?
Loop produce in ac frequency exp
When electrons in a magnet flowing in a closed loop stuck too a refrigerator doing work?
the magnet is supporting weight. I say yes.
Magnetic field due to a current through a circular loop?
The magnetic field due to a constant current through a circular loop is the same shape, outside the loop, as the field due to a bar magnet. At the centre of the loop the field can be found, using the Biot-Savart Law, to be (Equation 1: URL in related links), where ?0 is the permeability of free space, I is the current through the loop, R is the radius of the loop and z-hat is a unit vector perpendicular to the plane of the loop. The field on the axis of the loop can be found, again using the Biot-Savart Law, to be (Equation 2: URL in related links), where z is the distance from the centre of the loop along its axis and all other symbols have the same meaning as in the previous equation.
Why is closed loop recycling better than downcycling?
Because closed-loop recycling produces more recyclable materials.
