# Which method is applied to magnetic field?

## Which method is applied to magnetic field?

Magnetic field can be produced by any of the following methods: (i) Any magnet-bar magnet, horse-shoe magnet or round magnet can be used. (ii) A wire carrying current produces a field around it. (iii) A loop or solenoid carrying current.

## What is the best way to represent magnetic field?

Magnetic fields may be represented by continuous lines of force or magnetic flux that emerge from north-seeking magnetic poles and enter south-seeking magnetic poles. The density of the lines indicates the magnitude of the magnetic field.

What are the two methods for mapping the magnetic field lines?

Two methods used for mapping the magnetic field of a bar-magnet are: (i) Iron-filings method. (ii) Compass needle method.

### What are magnetic field lines?

Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet.

### What are the three ways to produce magnetic field lines?

Three different ways of producing magnetic fields are 1) A loop or solenoid carrying current. 2) A magnetic bar, round magnet or horse-shoe magnet. 3) A coil which carries current.

What is magnetic field and field line?

The magnetic field is an abstract entity that describes the influence of magnetic forces in a region. Magnetic field lines are a visual tool used to represent magnetic fields. They describe the direction of the magnetic force on a north monopole at any given position.

#### Can we see magnetic flux lines?

Solution: No, we cannot see magnetic flux lines as the “lines of magnetic flux” is purely an imaginary concept to understand the magnetic field clearly.

#### What is magnetic field and magnetic field lines?

magnetic field: the representation of magnetic forces B-field: another term for magnetic field magnetic field lines: the pictorial representation of the strength and the direction of a magnetic field direction of magnetic field lines: the direction that the north end of a compass needle points.

How do magnetic field lines work?

All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.

## How do you make a magnetic field line?

Following are the methods of producing magnetic fields:

1. By using a permanent magnet we can produce the magnetic field and it can be visualized by spreading iron fillings on a white paper and keeping a magnet beneath the paper.
2. A current-carrying straight conductor produces the magnetic field.

## Which device is used to find and draw the magnetic field lines?

Magnetic Compass is used to draw magnetic field lines.

How are magnetic field lines used to show magnetism?

Magnets repel and attract other magnets, and attract magnetic substances. Magnetic fields can be shown using field lines. Magnetism is induced in some materials when placed in a magnetic field. Magnets create magnetic fields. These magnetic fields cannot be seen.

### How can you tell the magnetic field of an iron filing?

Although we cannot see magnetic field lines, we can detect them using iron filings. The tiny pieces of iron line up in a magnetic field. Although we cannot see magnetic fields, we can detect them using iron filings. The tiny pieces of iron line up in a magnetic field.

### How do you make magnetic field lines clearer?

To solve this problem, iron filings are sprinkled onto paper or plastic over a magnetic field. One technique used to disperse the filings is to sprinkle them onto the surface from a height of a few inches. More filings can be added to make the field lines more clear, but only up to a point.

How can you see the path of a magnetic field?

Like air, a magnetic field is invisible. You can view wind indirectly by throwing small bits of paper into the air. Similarly, placing bits of magnetic material in a magnetic field lets you trace its path. Easy methods include:
