How force is directly proportional to length of a conductor?
Current flowing through the wire as the current in the conductor (I) is proportional to the force. Angle between the conductor and the external magnetic field as this determines the conductor’s effective length, or the vertical component of the length.
Does length of wire affect force?
The magnitude of the force on a current carrying conductor increases when the strength of the magnetic held is increased. The magnitude of the magnetic force also depends on the length of the wire in the magnetic field. The longer the wire in the magnetic field, the larger the force on the wire as shown in Figure.
Does magnetic field depend on length of wire?
The strength of the magnetic field depends on the current I in the wire and r, the distance from the wire. There is no real analogy to coulombs law for magnetism, as the magnetic field of a point charge is complicated since it can’t be standing still to generate a magnetic field.
What is the magnetic field due to an infinite linear current carrying conductor?
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.
What kind of magnetic field is found near a long straight wire?
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.
Which of the following best describes the magnetic field around a long straight current carrying wire?
No 1: Which of the following correctly describes the magnetic field near a long straight wire? Ans: According to right hand thumb rule the magnetic field lines, produced around a straight current-carrying conductor, are concentric circles.
Why do not two magnetic lines of force intersect each other?
Reason – The two magnetic field lines do not intersect each other because if they do, it means at the point of intersecting, the compass needle is showing two different directions, which are not possible.
Why are there no two magnetic fields?
Two magnetic field lines do not intersect each other because if there was point of intersection, The compass needle would point towards 2 directions. Which means that the magnetic field has two different directions, which is not possible.
