The magnetic field lines would be concentric circles with the wire passing through the centre perpendicular to the plane of the circles.
What is the shape of the magnetic field of a long straight wire?
The field around a long straight wire is found to be in circular loops .
Which describes the magnetic field lines near a long straight wire carrying current?
The magnetic field lines of a long straight wire are comprised of concentric circles centered around the wire . The direction of magnetic field lines is given by the right hand thumb rule.
How will you describe the magnetic field around a straight current carrying coil?
The magnetic field around a current carrying coil is produced due to the current flowing through it. It is uniform throughout . It is just like the magnetic field of a bar magnet. If needles of a magnetic compass are arranged around the coil, they will arrange themselves in North to South direction.
What is the magnetic field due to a straight wire?
Magnetic field due to an infinitely long straight current carrying wire – definition. B=(2πr)μ0I where B is the magnitude of magnetic field, r is the distance from the wire where the magnetic field is calculated, and I is the applied current.
Will the magnetic field be stronger in a straight wire?
The magnetic field is strongest in the area closest to the wire , and its direction depends upon the direction of the current that produces the field, as illustrated in this interactive animation. Presented in the tutorial is a straight wire with a current flowing through it.
Which of the following is correctly describes the magnetic field?
(D) The field consists of concentric circles centered on the wire . When charged particles flow through a conductor, there will be a magnetic field formed due to the movement of charges. It is given that we have a long straight wire that produces a magnetic field.
Who discovered the magnetic effects of current?
The magnetic effect of electric current was discovered by Hans Christian Oersted in the year 1982. On 21 April 1820, Oersted published his discovery that a compass needle was deflected from magnetic north by a nearby electric current, confirming a direct relationship between electricity and magnetism.
Why can’t two magnetic field lines cut each other?
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.
What is the shape of the magnetic field around a straight current carrying conductor?
Answer: The shape of magnetic field lines around a straight current carrying conductor is concentric circles . Right-Hand Thumb rule gives the direction of magnetic field produced by current carrying conductor.
How will you describe the strength of the magnetic field around the current carrying wire?
The Biot-Savart Law can be used to determine the magnetic field strength from a current segment. For the simple case of an infinite straight current-carrying wire it is reduced to the form B=μ0I2πr B = μ 0 I 2 π r . ... A current-carrying wire feels a force in the presence of an external magnetic field.
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.
Where is the magnetic field due to a straight current wire?
The magnetic field is along z-axis either in positive or negative z direction depending on the direction of current and whether observation point is on right or left of the current carrying straight wire.
What is the magnetic field symbol?
| symbol quantity SI unit | B, B magnetic field tesla | Φ B magnetic flux weber | N number of turns unitless | n turns per unit length, turns density inverse meter |
|---|
What is the magnetic field for infinitely long wire?
B=μ0I2πR . The magnetic field lines of the infinite wire are circular and centered at the wire (Figure 12.3. 2), and they are identical in every plane perpendicular to the wire. Since the field decreases with distance from the wire, the spacing of the field lines must increase correspondingly with distance.
What is the magnetic field due to a straight infinite current?
Magnetic field due to an infinitely long straight current carrying wire – definition. B=(2πr)μ0I where B is the magnitude of magnetic field, r is the distance from the wire where the magnetic field is calculated, and I is the applied current.
