∙ 14y agomotion occurs when an object changes its position relative to a reference point.
This is because the term "velocity" includes a specification both of a speed, and a direction. The direction changes, therefore the velocity changes.
At the highest and lowest extremes of its travel, at the points where it changes its direction of motion.
The motion along a straight line is known as rectilinear motion.
Motion directly either toward or away from the center is 'radial' motion. Motion where the distance from the center is constant is 'tangential' motion.
2 times per second x (2.5)= 5 volts 6 times per second x (2.5)=15 volts

A magnet induces an electric current in a wire coil when there is a relative motion between the magnet and the coil, which generates a changing magnetic field. This changing magnetic field induces an electromotive force, leading to the flow of an electric current in the wire coil.
When a magnet moves near a wire, it creates a changing magnetic field around the wire. This changing magnetic field induces an electric current to flow in the wire through electromagnetic induction. The current is only induced while there is a relative motion between the magnet and the wire, or if the magnetic field intensity changes.
Motion
Moving a bar magnet through a coil of wire induces an electromotive force (EMF) in the coil. This phenomenon is known as electromagnetic induction, according to Faraday's law. The induced current in the wire will produce a magnetic field that opposes the motion of the magnet, following Lenz's law.
Moving a magnet into a coil with more loops induces a stronger magnetic field, which in turn generates a larger induced current in the coil due to Faraday's law of electromagnetic induction. This induced current creates a magnetic field that opposes the motion of the magnet, resulting in increased resistance to movement. The resistor connected to the coil dissipates this induced current as heat, further impeding the magnet's motion.
Magnets attract steel paperclips because steel contains iron, which is a ferromagnetic material. When a magnet comes near a steel paperclip, it induces a magnetic field within the paperclip causing it to be attracted to the magnet.
This is an aspect of Lenz's law. Copper is a non magnetic substance but is a conductor. When a magnet moves through the copper pipe it induces a current known as eddy currents. There will be a magnetic field created by the current. According to Lenz's law it will oppose the motion or change which is producing it. This results in an attractive force between the magnet and the copper pipe in which a current is induced by the falling magnet. The plastic rod is not conducting and hence it will not affect the fall.
A microphone is a good example of a device that utilizes electromagnetic induction (Faraday's Law) to convert motion (vibrations in air) into electricity. The sound vibrates a membrane attached to a little magnet inside a coil of wire. The changing magnetic field induces a current in the wire.
Yes, when a magnet moves inside a wire loop, it creates a changing magnetic field which induces an electric current in the loop according to Faraday's law of electromagnetic induction. This current flows in the loop as long as the magnet is in motion.
A horseshoe magnet is used in a sonometer to create a magnetic field that can interact with a vibrating metal strip (sonometer wire) to produce sound. When the magnet is placed near the wire and the wire is set into motion, the changing magnetic field induces an electrical current in the wire, which creates vibrations that produce sound waves.
