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 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 magnetic field due to a current carrying conductor?

When current is passed through a straight current-carrying conductor, a magnetic field is produced around it. The field lines are in the form of concentric circles at every point of the current-carrying conductor.

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 shape of magnetic field due to current carrying long conductor?

Explanation: magnetic field lines are concentrated at the poles of a magnet or near a current carrying conductor magnetic field lines around a straight, electric current- carrying conductor are in concentric circles.

What is the relation between magnetic field current and distance?

The magnetic field at point P due to the element dl is found to be proportional to the current in the wire, and the length of dl and is inversely proportional to the square of the distance R . The magnitude of this field is given by, ⇒|d→B|=μo4πIdlsinθR2.

How can we find the direction of magnetic field due to a straight current carrying conductor?

The direction of magnetic field due to straight wire carrying current can be determined by right hand thumb rule. IF you grab the current carrying wire with your right hand. It such a way that thumb is in the direction of current, then the curled fingers show the direction of magnetic field.

What is the relationship between magnetic field B current 1 and distance r in 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 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.

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.

Does increasing current increase magnetic field?

The small magnetic fields caused by the current in each turn of the coil add together to make a stronger overall magnetic field. The strength of the magnetic field around a solenoid can be increased by: increasing the number of turns on the coil. increasing the current.

How do you calculate magnetic field?

The Biot-Savart Law can be used to determine the magnetic field strength from a current segment. 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 .

What is the shape of straight current carrying conductor?

The lines of magnetic field round a straight current-carrying conductor are in the shape of concentric circles.

What is the shape of the magnetic field line?

Magnetic field lines form in concentric circles around a cylindrical current-carrying conductor, such as a length of wire. The direction of such a magnetic field can be determined by using the “right-hand grip rule” (see figure at right).

What is the relation between magnetic force and current?

The magnetic force on a current in a magnetic field = current x displacement across the magnetic field. This force can be predicted using the right hand rule. When two currents are directed through magnetic fields in the same direction, they attract. When they are directed in the opposite directions, they will repel.
