A piece of any magnetic material, like iron or steel (a nail, knitting needle, bolt etc.) is take and placed on a bench or a table. A bar magnet is brought close to the magnetic material (say an iron piece AB). One end of the bar magnet is stroked against it, moving from end A to end B of the iron piece. When the bar reached end B, it is lifted and the stroke is repeated from A to end B. This procedure is repeated several times, keeping two things in mind:
(a) The same pole of the bar magnet should be used every time
(b) Strokes should be in the same direction
By stroking the iron piece with the north pole of the bar magnet, end A becomes the North Pole, and end B the South Pole. If you bring the South Pole of any magnet close to end A now, what will you observe? You will observe that the two attract, which simply proves that end A acquires the North Pole.

Three ways for increasing magnetic strength of solenoid?
refers to various ways of making a magnet from magnetic materials.they include: stroking method, electrical method, magnetism through hammaring among others*Induction *Stroking method : 2 types which are single touch method and double touch method *Electrical method ( By keeping the material to be magnetized in a solenoid and passing Direct current through it)The three methods to make magnet are:induction: the process of producing a electric or magnetic effects in a material with an electric charge or a magnet.stroking: is the process of rubbing in one direction.electricity: is a process to do with electric charge, particularly the use of electric energy.The three methods of making magnets are:1. Single touch method2. Double touch methodand by electrical method.
How do you reset a maximum and minimum thermometer with magnet?
Touch each end
What is double touch method of making magnet?
It was noticed that magnetizing a steel bar could be made easier by the use of the double touch method. Procedure: 1.Place a steel bar on a flat surface. e.g a table 2.Then two strong bar magnets are struck on the steel bar with their opposite poles striking the steel bar on either side AB.e.g the north pole of one magnet strikes side A and the south pole of another magnet strikes side B. 3.The magnets are moved to the centre and when they reach the centre,they are taken back to their original places in a magnetic field of way. 4.This stroke is repeated for several times until A and B gain a polarity. 5.You will notice that A will get the opposite polarity as B.i.e A will become the south pole while B will become the north pole.
Do magnets have to touch each other in order to experience a magnetic force?
not always as the south pole of a magnet is magnetic yet it repels another south pole. :D
When a magnet touch an iron nail does the nail becomes a temporary magnet?
The magnetic field would propagate through the material and extend itself for the length of the magnetic material in contact. As long as there is contact there is no pole present. When contact is broken the pole would be the opposite to the pole it was in contact with
How an iron nail can be made into a magnet using stroke method?
You stroke it with a magnet.That's how you turn a nail into a magnet.
Which method is better-single touch or double touch?
double touch method is better

What will happen to your iPod touch if a magnet touches it?
if a magnet makes any type of connection with your ipod touch, it will either disable your ipod or kill it!
Can two same sides of a magnet touch?
No.
Does a magnet need to touch the paper clips to excert and attractive force?
You need to do the experiment. If the magnet is strong enough, metal (steel, iron) will jump to the magnet (or pull the magnet towards it).
In building an electrical generator does the the magnet have to touch the spinning copper or does it not matter?
no, magnet needs to be close to winding, not touching it
What HAPPEND when you negative and negatives magnets touch?
Negative and negative sides of a magnet do not touch. opposites attract. Negative and positives touch.
When was Single Touch Systems created?
Single Touch Systems was created in 2001.
How do you reset a maximum and minimum thermometer with magnet?
Touch each end
Is there iron in plastics?
Plastic does not usually contain iron. You may have a plastic coated item. To verify, touch it with a magnet and see if the magnet sticks to it.
Why magnet is named as ferrous sulphide so?
Because you touch your self at night.
