You magnetize an iron needle permanently by stroking it with a strong bar magnet.
by stroking a magnet the right way you will make the magnet very happy, this will cause it to magnetise better, much like stroking a cat or dog. a happy magnet is a strong magnet
It is a magnet or a electro-magnet. If you are trying to use it as a metal detector then you will need a really strong magnet!
From my text book: You'll see that inside a solenoid the magnetic field is etremely strong, this can be used to magnetise objects. The field around it is exactly the same as the field around a bar magnet. Concentrated inside the solenoid and gradually getting more spaced out the further away
no
Why yes! Lodestone is magnetic! Lodestone is a form of iron. : )

by placing it in a strong magnetic field and hitting it with a hammer(please don't do this on working magnets as their strength will be decreased)
Just get a fairly strong magnet, I used a cow magnet. Wrap the magnet in a cloth so as not to scratch the face of the panel. Place the magnet over the needle and rotate it counter clockwise. If the magnet is strong enough the needle will return to its proper position.
rub against needle with strong magnet i guess 1. Hold a needle by the eye and stroke it gently 30 times with your magnet, in the same direction. Do the same with the second needle, making sure that you use the same end of the magnet. 2. Test your needle-magnets on some pins before you use them for other experiments.
Have fixed this issue many times... you need a STRONG magnet. Turn the ignition off, place the magnet over the gauge (on the clear plastic cover over the gauge cluster) on the end of the needle... it will react to the magnet and move when you move the magnet. Simply rotate the needle back into its proper position. Raise the magnet up... if it stays in the position, turn the ignition on... if your gauge is not broken, the needle should be reset and function properly.
you can take a magnet and run it down the side of you screw driver repeatedly. Screwdriver you can take 24 hours to attach a strong magnet. Or you can get away from the coil and plug wires to the battery.
A magnet can move a car, if the magnet is strong enough.
it creates a very strong magnet A+ users
strong

a magnet with many lines of force is STRONG
yes but it depends on the type of magnet and how strong it is
