What is the magnetic field at the centre of a circular loop?
The magnetic field at the centre of a circular loop carrying current is zero.
What is the magnetic field at centre C?
1 Answer. hence magnetic field at the centre is zero.
What is the formula of magnetic field class 12th?
Force on a moving charge [ Lorentz Force] (i) In magnetic field F=q(V x B)
What is the magnetic field at the centre of circle by using Biot Savart law give its formula?
The magnetic field at point P is calculated by the Biot-Savart law (Equation 12.2. 3): B=μ04πIΔlsinθr2=(1×10−7T⋅m/A)(2A(0.01m)sin(89.4o)(1m)2)=2.0×10−9T. From the right-hand rule and the Biot-Savart law, the field is directed into the page.
What is the value of magnetic field at the centre of a circular coil having n turns?
The magnetic field produced by a current-carrying wire at a given point depends directly on the current passing through it. Therefore, if there is a circular coil having n turns, the field produced is n times as large as that produced by a single turn.
What is the magnetic moment of the loop?
The magnetic dipole moment of the current loop is equal to the product of ampere-turns and area of current loop. It is denoted by M.
What is the magnetic moment of a revolving electron in a circular orbit?
Magnetic moment of an electron : μ=IA=2πrev×πr2=2evr.
What is the value of u0 4π?
Answer: value of u°/4π = 4π × 10−7 H/m ≈ 12.57×10−7 H/m.
How do you find the direction of magnetic field on the axis of a circular loop?
State right-hand thumb rule. The right-hand thumb rule states that “Curl the palm of your right hand around the circular wire with the fingers pointing in the direction of the current. The right-hand thumb gives the direction of the magnetic field”.
Is the magnetic field of a circular loop uniform?
Solution : Magnetic field due to current through circular loop is uniform at the centre of the current loop and non-uniform near the circular coil.
Why do magnetic field lines not form a circular loop?
The magnetic field distribution within the planar surface of a loop is not a simple equation, usually calculated by long term integral of physical location of the observing point, it is a long term because that position is not circularly symmetrical to obtain a small termed function.
What is the magnetic dipole moment of a circular loop?
θ 3 R where μ=iA is the magnetic dipole moment of the loop sin B = μ ⎪ ⎩ θ 0 4 π R 3 Here i is the current in the loop, A is the loop area, R is the radial distance from the center of the loop, and θ is the polar angle from the Z-axis. The field is equivalent to that from a tiny bar magnet (a magnetic dipole).
Why is the magnetic field of a wire circular?
Hence the magnetic field lines are also distributed along the length of the wire. If we now bend the wire into a circular loop however, the current elements come closer together and hence the magnetic field lines add up, increasing the flux density.
How do you calculate magnetic field?
– extremes of temperature and humidity; – insufficient distance of the probe from the investigator; – instability in meter position; – loss of non-conductive properties of the supporting rod.
