How can you use a magnet to induce a current?
You can induce a current in a wire by moving the magnet in and out of the coil or by moving the coil near the magnet. The changing magnetic field created by the moving magnet induces a current in the wire according to Faraday's law of electromagnetic induction.
What a moving magnet makes?
makes current flow through a magnet
What are the types of galvanometer?
The two main types of galvanometers are moving coil galvanometers and moving magnet galvanometers. Moving coil galvanometers use a coil of wire that moves in a magnetic field, while moving magnet galvanometers use a magnet that moves in a coil of wire.
How does a record player work?
Are you talking direct-driven, belt-driven, or clockwork driven (Gramophone) type of turntable, they all work differently.A clockwork-driven Gramophone uses a spring motor to drive the turntable, that would have to be wound-up to drive the turntable. A governor kept the speed of the constant and a speed control flywheel slowed or increased the speed of the turntable. The motor has a shaft that turns and the turntable is attached to the shaft, which spins the record that rests on the turntable. The reproducer with needle picks up the vibrations that are recorded in the bumps and curves in the record groove. The vibrations travel up the needle, through the reproducer, and to a diaphragm that vibrates to produce sound travels through a tube and out the horn.Modern Belt-drive turntables use an electric motor connected to a shaft that used a spring to turn the turntable. The Speed is changed by the motor speed either being increased or decreased. When using a ceramic cartridge, the movement of the needle back and forth in the groove bends tiny ceramic bars that produce minute electrical impulses, which are strengthened by an amplifier, which is then sent to an electromagnetic speaker. When using a "Moving-Magnetic" cartridge, the needle moving back and forth and up and down in the groove moves tiny magnets against each other producing electrical currents which are again strengthened by an amplifier and sent to speakers. When using a "Moving-Coil" cartridge, the needle compresses and retracts little springs that are attached to magnets which produce little electrical pulses, which are sent through an amplifier and to the speakers.A direct-drive turntable works almost like a Belt-drive, but the mechanism is a little different. The motor is attached to a tiny rubber-idler wheel which is touching the shaft that turns the turntable; when the idler spins 139 times faster than the turntable. The speed of the motor never changes, the speed-change is managed by moving the idler up the shaft (Faster Speed) or down the shaft (Slower Speed). Many direct-drive turntables also have a speed adjustments that move the idler by fine amounts (usually -0.5 and +0.5 RPM).
Why does a magnet slow down when moving through a copper tube?
A magnet slows down when moving through a copper tube because the magnetic field generated by the moving magnet induces electric currents in the copper tube, creating an opposing magnetic field that resists the motion of the magnet. This resistance, known as electromagnetic induction, causes the magnet to slow down as it moves through the tube.
Generating and inducing an electric current can be done through?
a moving coil and moving magnet
Can a magnet pull a fast moving roller coaster?

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.
