The double touch method involves stroking a ferrous material (such as iron) with a magnet in the same direction twice. This aligns the magnetic domains within the material, creating a temporary magnet. The material will only remain magnetic while in contact with the original magnet.
What else can I help you with?
What are the single and double touch methods for magnetizing an un magnetized magnetic material?
The single-touch method involves rubbing a magnet along the length of the material in one direction. The double-touch method involves alternating the direction of the rub after each stroke along the length of the material, effectively exposing both ends of the material to the magnetic field. Both methods help align the magnetic domains within the material, resulting in magnetization.
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).
What happens when you touch a piece of iron to a permanent magnet?
When you touch a piece of iron to a permanent magnet, the iron can become magnetized temporarily because it can align its domains with the magnetic field. However, once the iron is removed from the magnet, it will lose its magnetism over time. The iron itself does not retain a permanent magnetism like the original magnet.
When you touch a magnet to a steel nail the nail attracts steel paper clips. Explaine why this does not happen when you use an aluminum nail?
it wouldn't be magnet to a aluminum nail because the aluminum is not a way of magnet and a steel nail would because steel is a way of magnet.
Why doesn't the magnet have to touch each object?
A magnetic field is created around the magnet that can attract objects without physical contact. This field can extend some distance from the magnet, allowing it to influence objects nearby without directly touching them.
Which method is better-single touch or double touch?
double touch method is better
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.
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 an iron nail can be made into a magnet using stroke method?
To magnetize an iron nail using the stroking method, you can stroke the nail with one end of a magnet in a consistent direction many times. This allows the domains in the iron to align in the same direction, creating a magnetic field in the nail. The nail will then act like a magnet with a north and south pole.
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
Single touch method of making magnet?
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.
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.
Why magnet is named as ferrous sulphide so?
Because you touch your self at night.
What happens when you touch a piece of iron to a permanent magnet?
When you touch a piece of iron to a permanent magnet, the iron can become magnetized temporarily because it can align its domains with the magnetic field. However, once the iron is removed from the magnet, it will lose its magnetism over time. The iron itself does not retain a permanent magnetism like the original magnet.
