List of Properties of Magnetic Field Lines: The magnetic field is a field produced by the magnet or electric charges in motion. list the properties of magnetic field lines class 10 The magnetic field is the region around a magnetic material or moving electric charge within which the force of magnetism acts. Magnetic fields are represented using magnetic field lines. It is a visual tool used to visualize the direction and the strength of the magnetic field. Magnetic field lines can be drawn using a compass needle. Then the compass needle should be placed on a piece of paper near the magnet. Check the direction in which the compass needle points and mark the direction. Move the compass needle to different positions and mark the directions. Joining the points shows the magnetic field lines.
In Hindi:
चुंबकीय क्षेत्र गति में चुंबक या विद्युत आवेशों द्वारा निर्मित एक क्षेत्र है। चुंबकीय क्षेत्र एक चुंबकीय सामग्री या गतिमान विद्युत आवेश के आसपास का क्षेत्र है जिसके भीतर चुंबकत्व का बल कार्य करता है। चुंबकीय क्षेत्र रेखाओं का उपयोग करके चुंबकीय क्षेत्र का प्रतिनिधित्व किया जाता है। यह एक दृश्य उपकरण है जिसका उपयोग चुंबकीय क्षेत्र की दिशा और ताकत की कल्पना करने के लिए किया जाता है। कम्पास सुई का उपयोग करके चुंबकीय क्षेत्र रेखाएँ खींची जा सकती हैं। कम्पास सुई को चुंबक के पास कागज के एक टुकड़े पर रखा जाना चाहिए। उस दिशा की जाँच करें जिसमें कम्पास सुई इंगित करती है और दिशा को चिह्नित करती है। कम्पास सुई को विभिन्न स्थितियों में ले जाएँ और दिशाओं को चिह्नित करें। बिंदुओं को मिलाने से चुंबकीय क्षेत्र रेखाएँ दिखाई देती हैं।
List of Properties of Magnetic Fields Lines
- The Magnetic Field lines are like closed curves.
- Closer the field lines, the stronger the magnetic field and vice-versa.
- The magnetic field lines are crowded near the poles and widely apart at other places.
- The magnetic field lines do not intersect each other. list four properties of magnetic field lines

Features of Magnetic Field Lines
- Magnetic field lines form a closed loop.
- Field lines have both direction and magnitude at any point on the field. Therefore, magnetic field lines are represented by a vector.
- They denote the direction of the magnetic field.
- The magnetic field is stronger at the poles because the field lines are denser near the poles.
Magnetic field and Field Lines
The impact of power encompassing a magnet is called a magnetic field. In the magnetic field, the power applied by a magnet can be identified by utilizing a compass or some other magnet. The non-existent lines of the magnetic field around a magnet are called field lines or field lines of magnets. At the point when iron filings are permitted to settle around a bar magnet, they get masterminded in an example which emulates the magnetic field lines. The field line of a magnet can likewise be identified utilizing a compass. The magnetic field is a vector amount, for example, it has both direction and size.
The direction of Field Line: Outside the magnet, the bearing of the magnetic field line is taken from the north pole to the South Pole. Inside the magnet, the course of the magnetic field line is taken from the south pole to the north pole.
Strength of magnetic field: The closeness of field lines shows the overall strength of the magnetic field, for example, closer lines show a more grounded magnetic field and the other way around. Swarmed field lines close to the posts of magnets show more strength.

Magnetic field Due to a Current-Carrying Conductor
Magnetic field because of current through a straight conductor: A current conveying a straight conductor has a magnetic field as concentric circles; around it. The magnetic field of the current conveying straight conductor can be appeared by magnetic field lines.
The bearing of the magnetic field through a flow conveying transmitter relies on the direction of the stream of electric flow. The course of the magnetic field gets switched if there should be an occurrence of a shift in the bearing of electric flow.
Let a flow conveying conveyor be suspended upward and the electric flow is move from south to north. For this situation, the course of the magnetic field will be anticlockwise. Then on the off chance that the current is moving from north to south, the bearing of the magnetic field will be clockwise.

Right-Hand Thumb Rule: Maxwell’s Wine Tool Rule
The direction of the magnetic field; corresponding to the bearing of electric flow through a straight conduit can be portrayed by utilizing the Right-Hand Thumb Rule. So iIt is otherwise called Maxwell’s Corkscrew Rule.
On the off chance that a flow conveying channel is held by the right hand; keeping the thumb straight and assuming the course of electric flow is toward the thumb, the bearing of wrapping of different fingers will show the direction of the magnetic field. So according to Maxwell’s wine tool rule, if the bearing of the positive headway of the screw shows the course of the current, at that point the direction of revolution of the screw shows the course of the magnetic field.
Properties of Magnetic Field
If a roundabout current should be incident to a conducting conductor, the magnetic field lines would form concentric circles around all facets of the conductor’s exterior. Since the magnetic field lines are usually closed when they are near the conductor, the magnetic field will be closer to the fringe of the circle. Then, as we move towards the centre point of the current convection circle, the magnetic field lines are far apart from each other. eventually; So in the middle, circular segments of giant circles will appear as a straight line.
Then the effect of the magnetic field can be recognized using the thumb rule of the right hand. Allow us to expect that the current is bearing clockwise over the enemy. Around there, the magnetic field would be in a clockwise direction; at the highest point of the circle. Additionally, it will be counter-clockwise at the bottom of the circle.
Some Rules
Clock Face Rule: The current convection circle plate acts like a magnet. Then the end of this magnet can be easily seen with the help of the clock face rule. Assuming that the current is flowing in the clockwise direction of the enemy, the material of the circle represents the North Pole. Then again, in the event that the current is flowing clockwise, the essence of the circle represents the South Pole.
Magnetic field and number of turns of the loop: The magnitude of the magnetic field is summarized with the extension in the number of turns of the curl. If there are ‘n’ turns of the loop, then the size of the magnetic field in the case of a single twist of the curl will be ‘n’ seasons of the magnetic field.
Magnetic Field Due to Current in Solenoid: The solenoid is curled with many circular coils of shielded copper wire that look like a chamber. Then a current-conveying solenoid produces a comparable example of a magnetic field as a bar magnet. Then one end of the solenoid acts as the north pole and the other end as the south pole. The magnetic field lines inside the solenoid are equal; Like a bar magnet; Which shows that the magnetic field is uniform and concentrated inside the solenoid. So by distributing a solid magnetic field inside the solenoid, the magnetic material can be charged. A magnet created by distributing a magnetic field inside a solenoid is called an electromagnet.

FAQs
What material can block a magnetic field?
MuMetal® is the most widely used alloy for magnetic shielding purposes. Its composition of 80% nickel, 4.5% molybdenum and balanced iron give it highly permeable properties. This tells us that the material has high magnetic susceptibility to an applied magnetic field; it readily accepts the flow of the magnetic field
What causes some materials to have magnetic fields?
Magnetism is caused by the motion of electric charges. Every substance is made up of tiny units called atoms. Each atom has electrons, particles that carry electric charges
How do magnets lose their properties?
At around 80 °C, a magnet will lose its magnetism and it will become demagnetized permanently if exposed to this temperature for a period, or if heated above its Curie temperature. Heat the magnet even more, and it will melt, and eventually vaporize
What is the strength of the magnetic field?
Magnetic field strength also called magnetic intensity or magnetic field intensity is the part of the magnetic field in a material that arises from an external current and is not intrinsic to the material itself. So it is expressed as the vector H and is measured in units of amperes per metre.
Where is the magnetic field the strongest?
Magnetic poles are opposite ends of a magnet where the magnetic field is strongest. list two properties of magnetic field lines
