Equation: B = μ0 * I / (2 * π * d) where: I - current d - distance from the wire B - strength of the magnetic field produced at distance d μ0 - constant value μ0 = 4 * π * 10^(-7) [T * m / A] permeability o
The velocity field is affected by the magnetic field of a wire carrying the electric current. The geometry of the problem is two-dimensional squares, that the left and right sides are at temperatures Th and Tc, respectively (Th>Tc). In addition, the upper and lower walls are insulated. ...
7.3A is an attempt. Try to think in three dimensions. Current flow in the antenna wire creates the magnetic field lines. The voltage across the two segments of the antenna produces the electric field lines. The picture is somewhat simplified if we just show the field lines as in Fig. 7.3...
Wire magnetic field In the case of an electric current passing through a loop, the magnitude of magnetic field equation at the loop center is: {eq}B=\frac {\mu _{0}*I}{2*R} {/eq}, where R here is the loop radius measured in meters (m).The...
Curious to see what a solenoid is and how to calculate the magnetic field of a solenoid? Just continue reading. You will also learn about the solenoid magnetic field equation. What is a solenoid? If we run a current through a wire, there is a magnetic field around it. A solenoid is a...

Magnetic Force Acting on a Current-Carrying Conductor If a magnetic force is exerted on a single charged particle when the particle moves through a magnetic field, it should not surprise you that a current-carrying wire also experiences a force when placed in a magnetic field. Let us di...
Step 3:Find the direction of the magnetic field by curling the other fingers in your right hand, the resulting shape represents the direction of the magnetic field. What is the Right-Hand Rule for a Current-Carrying Wire? Right-Hand Rule:For a wire carrying a uniform current, the r...
