the needle will have a magnetising pull by steeling the magnetic energy from the magnet
Rub the needle across a magnetic surface...always in the same direction, don't go back and forth. This will magnetise the needle. Then float the needle in a dish of water. And presto you have your own compass
When you move the magnet back and forth near a coil of wire, it induces an alternating current in the wire. The direction of this induced current changes as the magnet moves due to Faraday's law of electromagnetic induction, which states that changing magnetic fields induce an electromotive force (emf) in a conductor.
When you move a magnet back and forth inside a coil of wire, it induces an electric current to flow in the wire. This process is known as electromagnetic induction and is the principle behind how electric generators work. The strength of the induced current is determined by the rate of change of the magnetic field.
The bar magnet rotates instead of oscillates because the magnetic forces acting on it cause it to align with the magnetic field, leading to a rotational motion rather than a back-and-forth oscillation.
A bouncing speedometer needle could be caused by a loose or damaged speed sensor cable, a faulty speed sensor or a problem with the instrument cluster. It is best to have a mechanic diagnose and repair the issue.

You are trying to align the magnetic domains in the metal. Going in one direction helps this to occur. Going back and forth will result in a net zero domain alignment.

Get on the magnet train and it will take you to Goldenrod city. You can back and forth between johto and kanto easily using the magnet train, but it's not essential.

Round and round for a hen, back and forth for a rooster
If two tectonic plates rub back and forth against each other, they can create friction that builds up stress. This stress can eventually be released in the form of an earthquake when the plates suddenly slip past one another. The movement can also lead to the formation of mountain ranges or ocean trenches.
Needs new speed sensor or if it has a cable to the speedometer it needs to be replaced along with the housing.

yes, it will be very small but the inductance from the magnet should stimulate a current in the wire as it will cause electrons to move.
If the speedometer needle is going crazy and not working properly, it is probably the speedometer mechanism that needs to be replaced. It could also mean the vehicle is having a transmission slippage problem if the needle is bouncing back and forth.
