The direction of the magnetic field is tangent to the field line at any point in space. A small compass will point in the direction of the field line. The strength of the field is proportional to the closeness of the lines.
What is the direction of magnetic field at a given point?
The direction of Magnetic field lines at a given point is from NORTH POLE to SOUTH POLE .
What is the magnetic field at a point?
The field at a point on the axis is parallel to axis itself . The direction may be obtained as follows. Curl the fingers of your right hand in the direction of flow of current The direction in which thumb points gives you the direction of magnetic field at that point.
What is the direction of magnetic field at a given point Class 10?
The North – pole of the compass specifies the path of a magnetic field at that point. Note: To understand the compass we know about the magnetic properties of the magnet. According to the properties of the magnet, these field lines always go to the North Pole and the South Pole.
What is the direction of magnetic field at point P and Q?
By applying the right-hand thumb rule, the direction of magnetic field would be anti-clockwise as shown in diagram around the direction of current. So, the magnetic field at point P would be into the plane of paper. At point Q, the direction of magnetic current would be out from the plane of paper.
Which direction does the magnetic field point at location 2?
Using the right-hand rule to determine the direction of the magnetic field around a wire, the magnetic field will point in the clockwise direction .
What is the magnetic field at point 0?
Magnetic field due to straight wires=0 .
Why can’t magnetic field lines cross?
The magnetic field lines never intersect each other because if two or more lines intersect each other than it means that at that point of intersection, the magnetic field has two directions at the same point . This is not possible for a magnetic field to point in more than one direction at the same point.
Where is the magnetic field the strongest?
The strongest external magnetic fields are near the poles . A magnetic north pole will attract the south pole of another magnet, and repel a north pole.
What is Fleming’s left hand rule?
Fleming’s left – hand rule states that if we stretch the thumb, middle finger and the index finger of the left hand in such a way that they make an angle of 90 degrees(Perpendicular to each other) and the conductor placed in the magnetic field experiences Magnetic force.
What are the two methods of producing magnetic field?
- 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.
- A current-carrying straight conductor produces the magnetic field.
What is necessary to have a magnetic field?
for magnetic field we have continuous flow of charge particle . ... but for magnetic field it must be in motion . Magnetic field is always perpendicular to the Electric field. hence current is flow i.e. charge is flow then magnetic field is produced.
Under what conditions permanent electromagnet is obtained?
A permanent electromagnet is obtained under the following conditions if a current carrying solenoid is used: The core of the the current carrying solenoid must contain metallic core (like steel or iron) with the high capability to retain magnetic properties a long time after magnetization.
When a magnetic field is applied on a stationary electron it?
A stationary electron cannot make current . As the electric field is steady, there is no magnetic field. The magnetic field B is defined in terms of force on moving charge in the Lorentz force law. The SI unit of the magnetic field is Tesla.
How will the magnetic field produced at point P?
We know that the magnetic field produced by a current carrying wire at a given point depends directly on the current passing through it . So if we increase the number of turns of the coil, more current will pass through the wire which indicates that the magnetic field associated with it also increases.
