What is magnetic field around a straight conductor?
The nature of the magnetic field lines around a straight current carrying conductor is concentric circles with centre at the axis of the conductor. The direction of the magnetic field lines of force around a conductor is given by the Maxwell’s right hand grip rule or the right handed corkscrew rule.
What is the magnetic field due to a long straight wire?
For an infinitely long straight wire, the magnetic field lines are circles centered on the wire. The direction is given by a right-hand rule: With your right hand, point your thumb in the direction of the current. When you curl your fingers they curl in the direction of the magnetic field.
What is the formula of magnetic field due to straight wire?
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 . It is found to be F=Bilsinθ F = Bi l sin θ , where ℓ is the length of the wire, i is the current, and θ is the angle between the current direction and the magnetic field.

How we measure the magnetic field due to straight current carrying conductor?
Right hand thumb rule If holding straight wire with right hand so that the extended thumb points in the direction of current, then curl of the fingers gives the direction of magnetic field around the straight wire.
How does the magnetic field due to straight conductor vary if electric current become double *?
The magnetic field strength will quadruple.
How is the magnetic field of a current carrying straight conductor?
The magnetic field produced by a current-carrying straight wire depends inversely on the distance from it and directly on the current passing through it. From this we see that the current carrying conductor produces a magnetic field around it. The direction of this magnetic field is given by Right Hand Thumb Rule.
What kind of magnetic field is produced due to straight solenoid?
Answer: The kind of magnetic field formed due to a straight current carrying solenoid is similar to the magnetic field due to bar magnet of similar dimensions.

What is magnetic field due to current?
The force of magnetism is due to moving charge or some magnetic material. Like stationary charges produce an electric field proportional to the magnitude of charge, moving charges produce magnetic fields proportional to the current. In other words, a current carrying conductor produces a magnetic field around it.
What is the conclusion of magnetic effect of electric current?
Conclusion: Passing an electric current in a coil wrapped around an iron piece makes the iron piece magnetic. The strength of the electromagnet depends on the number of turns of the wire around the core and the amount of current passing through it. The more the number of turns, the more will be the magnetic effect.
How is the magnetic field of a straight current carrying conductor?
For an infinitely long current-carrying conductor, the value of a a is large enough that we can neglect x x entirely, that is for a >> x a >> x, the magnetic field is The magnetic field is proportional to the distance from the wire, that is it decreases by increasing the distance from the wire.
How is a magnetic field different from an electric field?
The difference between electric and magnetic fields of straight current carrying conductor is that the electric field is radially outward but the magnetic field surrounds the conductor in circles as illustrated in Biot-Savart law.
Why is the magnetic field of a compass always perpendicular to the current?
Since compasses work by pointing along magnetic field lines, this means that there must be a magnetic field near the wire through which the current is flowing. The magnetic field produced by an electric current is always oriented perpendicular to the direction of the current flow.
How to find the relationship between current and magnetic field?
There is a simple method of finding the relationship between the direction of the current flowing in a conductor and the direction of the magnetic field around the same conductor. The method is called the Right Hand Rule.
