What is the value of magnetic field at a point on a straight thin current carrying wire?

What is the value of magnetic field at a point on a straight thin current carrying wire?

Hence the magnetic field induction at any point on the conductor itself is zero. Punjab Cooperative bank recruitment 2021 notification out, apply for 856 posts.

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.

What is the relation between magnetic field B current I and distance R in the case of a straight current carrying conductor?

Answer: 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.

What is the nature of the magnetic field due to a circular coil?

Answer. Answer: The direction of magnetic field lines are straight and the direction of magnetic field at the centre of circular coil is perpendicular to the place of the coil.

What is the magnitude and direction of the magnetic field inside the current carrying solenoid?

(a) Because of its shape, the field inside a solenoid of length l is remarkably uniform in magnitude and direction, as indicated by the straight and uniformly spaced field lines. The field outside the coils is nearly zero. (b) This cutaway shows the magnetic field generated by the current in the solenoid.

What law gives the direction of induced current?

Lenz’s law is used for determining the direction of induced current. Lenz’s law of electromagnetic induction states that the direction of induced current in a given magnetic field is such that it opposes the induced change by changing the magnetic field.
