n(89.4o)
(1m)2)=2.0×10−9T.
What is the value of magnetic field at a point on a straight thin current carrying wire?

is zero
.
What is the value of magnetic field due to a straight current carrying conductor of infinite length at a perpendicular distance a from the conductor?
For the long or infinite length of the straight wire or any conductor, the perpendicular distance from the wire is at the center of the wire that
φ1=φ2=90∘
.
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.
How do you find the magnetic field at a point?
The magnetic field at point P is calculated by the Biot-Savart law:
B=μ04πIΔlsinθr2=(1×10−7T⋅m/A)
(2A(0.01m)sin(89.4°)(1m)2)=2.0×10−9T. From the right-hand rule and the Biot-Savart law, the field is directed into the page.
Where is the magnetic field the strongest?
But we know the field inhabits all the space around the magnet. It is strongest at
the poles
. So, what are magnetic poles? Magnetic poles are opposite ends of a magnet where the magnetic field is strongest.
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 equation for magnetic flux density?
More lines means a stronger attractive force. The equation for calculating the force on a wire is Force (N) = magnetic flux density (T) × current (A) × length (m) or, in short
F = B I L.
What is the formula of magnetic field?
The magnitude of the force on a wire carrying current I with length L in a magnetic field is given by the equation.
F=ILBsinθ
where θ is the angle between the wire and the magnetic field. The force is perpendicular to the field and the current.
At what distance does a long straight wire carry a current?
The answer is
1.71 cm
.
What is Biot Savart’s law?
Biot Savart law states that
the magnetic field due to a tiny current element at any point is proportional to the length of the current
element, the current, the sine of the angle between the current direction and the line joining the current element and the point, and inversely proportional to the square of the …
What is relation between magnetic field current and distance in case of straight current carrying conductor?
Magnetic field strength is inversely proportional to the distance from the wire
i.e. begin{align*}B propto frac{1}{r}end{align*}, greater the distance from the current carrying conductor, weaker will be the magnetic field.
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.
Is magnetic field infinite?
Researchers from the Complutense University of Madrid (UCM, Spain) have mathematically shown that
particles charged in a magnetic field can escape into infinity without ever stopping
. One of the conditions is that the field is generated by current loops situated on the same plane.
What is the magnetic field of an infinite 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.
