What is the magnitude of the magnetic field due to the long straight wire at a distance r away from it?

The magnitude of the magnetic field field a radial distance r away from a long, straight wire is B = μ0I/(2πr). Details of the calculation: B = (4π*10-7 N/A2)*30 A/(2π*0.01 m) = 1.2*10-5/*0.02 = N/(As) = 5*10-4 T.

How do you find the magnetic field of a long straight wire?

For the case of a long straight wire carrying a current I, the magnetic field lines wrap around the wire. By pointing one’s right thumb along the direction of the current, the direction of the magnetic field can by found by curving one’s fingers around the wire.

What is the magnitude of magnetic force per unit length on a wire carrying a current of 8 A?

0.6 N m-1
What is the magnitude of magnetic force per unit length on a wire carrying a current of 8 A and making an angle of 30º with the direction of a uniform magnetic field of 0.15 T? Angle between the wire and magnetic field, Ω¸ = 30°. Hence, the magnetic force per unit length on the wire is 0.6 N m-1.

At what distance from a long straight wire carrying a current of 12 A will the magnetic field be equal to 5 2 3 10bb?

Hence, at 0.08 m from a long straight wire carrying a current of 12 A.

What is the magnetic field for infinitely long wire?

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.

How do you find the magnitude of a 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.

What current must flow in an infinitely long wire?

Calculation: General expression of magnetic field intensity (or flux density) for infinite wires is: So, current through wire is 9 Ampere.

How is Biot Savart law useful?

We can use Biot–Savart law to calculate magnetic responses even at the atomic or molecular level. It is also used in aerodynamic theory to calculate the velocity induced by vortex lines.
