Calculate the inductance using the following formula: Inductance = µ (N squared) A / length, where N is the number of turns in the coil, A is the cross-sectional area of the coil, and length is the length of the coil. µ (or "mu") is a constant called the vacuum permeability ...
The approach is an algebraic method where a field vector is generated for the test currents of each coil (20). Vector and matrix algebra is applied and a linear set of equations is formed. Field components and their derivatives up to the desired order can be taken into account. Principal ...
You can calculate the amount of wire of width W needed to make a coil of radius R and length L by using the formula 2?R x (L/W). This formula is equivalent to the circumference each loop of the wire makes times the number of such loops in the coil. This formula is, however, a...
The original problem is to calculate the Induced voltage of receive coil when transmit coil have a current souce with frequency 20 kHz. The coils have hundreds turns which can't be acted a point, so that if we calculate the induced voltage by integrating the electrical field along the circle...
Step 2:Using the equation, {eq}L = \frac{{\mu}N^{2} A}{l} {/eq}, to calculate the inductance of a solenoid. What is a Solenoid and Inductance? How can you Calculate the Inductance of a Solenoid? Solenoid:It is defined as a coil of metal wire, usually with a cylindrical shape...
to a coil, or coils, carrying a current. A time-varying current flowing in the coil creates a time-varying magnetic field, which in turn induces a time-varying E-Field, a phenomenon known as electromagnetic induction2. The amplitude of the E-Field induced in the culture medium by ...

channels45. Below, we calculate the mechanical forces and stress in a cell placed in an HGMF. The volume density of the magnetic gradient force (in Nm−3) acting on a cell is where χmis the susceptibility of the medium, χcis the susceptibility of the cell, and μ0is the vacuum ...
Put the coil near to a big, permanent magnet and the temporary magnetic field the coil produces will either attract or repel the magnetic field from the permanent magnet. If the coil is free to move, it will do so—either toward or away from the permanent magnet. In an electric motor, ...
A metal detector search coil is the rounded coil of wire on the end of the metal detector. The coil is fed a signal by the electronics in the body of the detector and transmits to the area surrounding it via an oscillating electromagnetic field. When the
