2023年1月16日 · \(\vec{A}\) is the area vector of the loop or coil. Its magnitude is the area of the plane shape whose perimeter is the loop or coil. Its direction is the direction your extended right thumb would point if you curled the fingers of your right hand around the loop in …
Direction of the Area Vector (with regards to magnetic dipole)
I'm learning about torque on a conductive coil in a magnetic field. I have been taught that $\vec\tau = \vec\mu \times \vec{B}$, where $\vec\mu$ is the magnetic dipole moment. Also, $\mu = I\vec{A}$, where $\vec A$ is the area vector of the loop.

The magnetic moment (or magnetic dipole moment) is a vector. The direction of the magnetic moment is the direction of the area vector of the loop as defined by the right-hand rule. Curl the fingers of your right hand in the direction of the current flow.
22.1: Magnetic Flux, Induction, and Faraday’s Law
vector area: A vector whose magnitude is the area under consideration, and whose direction is perpendicular to the surface area. galvanometer: An analog measuring device, denoted by G, that measures current flow using a needle deflection caused by a magnetic field force acting upon a current-carrying wire.
Area of a Coil Calculator
In the field of Physics, specifically within electromagnetism, the concept of the coil area is paramount in the study of electric circuits, generators, transformers, and inductance. This tutorial will delve into the calculation of the area of a coil, often vital in electromagnetic applications and the design of electrical devices.
In a physics lab experiment, a coil with 200 turns enclosing an area of 12 cm2 is rotated in 0.04 sfrom a position where its plane is perpendicular to the earth’s magnetic field to a position where its plane
Experimentally it is found that the induced emf depends on the rate of change of magnetic flux through the coil. Let the area vector be A = A n ˆ , where A is the area of the surface and ˆn its unit normal. The magnetic flux through the surface is given by. and ˆn . …
In this experiment you will measure the magnetic eld of a circular coil at distances that are fairly close to the coil, so the large distance approximation is not valid. constant magnetic eld can be measured in many ways; you can use a compass, a Hall Probe, a rotating coil of wire, or nuclear magnetic resonance.
Define a vector A whose magnitude is the area of the coil's face and whose direction is perpendicularly out from the face (see Figure 19.2). With A so defined (note: this variable will sometimes be denoted as S, standing for surface area--we will use both notations), the magnetic flux through the coil's face is: Φm. e.)
A Helmholtz coil arrangement consists of two current-carrying conductor rings in the same direction on a common axis. For an optimal homogeneous magnetic field between the coils, we must choose the coil radius and distance equal. We calculate the magnetic field lines in the x-z plane, plot them, and compare them to the experiment.
