How could you magnetise a needle to make your own compass?
To magnetize a needle to make a compass, you can rub the needle on a magnet in the same direction multiple times. This will align the magnetic domains in the needle and make it magnetic. Once magnetized, the needle will point towards the Earth's magnetic North pole, allowing it to act as a simple compass.
What happens to the direction of the current when you move the magnet back and forth?
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.
What happens when you move a magnet back and forth inside a coil of a wire?
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.
What causes speedometer needle to bounce back and forth?
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.
What magnet is used to convert sound into electrical signals?
A microphone uses a magnet known as a diaphragm to convert sound waves into electrical signals. The diaphragm vibrates in response to sound waves, causing changes in the magnetic field and generating an electrical signal proportional to the sound.
What would happen if two tectonic plates rubbed back and forth against each other?
an earthquake happens

What will happen if a nail were stroke back and forth with a magnet instead of circular motion?
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.
Which of these will always happens when sandpaper is rubbed back and forth on a piece of wood?
The wood changes color
What do you do after you get the magnet train pass on Pokemon heart gold?
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.

What way does a needle turn above an egg for a rooster?
Round and round for a hen, back and forth for a rooster
What would happen if two plates rubbed back and forth against each other?
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.
Speedometer needle jumps back and forth?
Needs new speed sensor or if it has a cable to the speedometer it needs to be replaced along with the housing.

A horseshoe magnet is moved back and forth across a piece of copper wire an electric current is detectable in the wire?
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.
What is wrong with the car when the speedometer needle goes crazy and you don't know how fast you're going?
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.
