# Magnetic field due to current sheet metal prices

ponent of the flaw-induced magnetic field using the 5 Il (2 mils) thick copper current-sheet. The distribution of the normal component of the magnetic field on the left hand side of the center hole is due to the rotational component of the electric currents around the hole. Application to Current Sheet Example 3.6: Let us now use Ampere’s Circuital Law to find the magnetic field intensity resulting from an infinite extent sheet of current. Let us consider a current sheet with uniform current density K = K xa x in the z = 0 plane along with a rectangular Amperian Path of height ∆h and width ∆w. The magnetic field exerts a force on a current-carrying wire in a direction given by the right hand rule 1 (the same direction as that on the individual moving charges). This force can easily be large enough to move the wire, since typical currents consist of very large numbers of moving charges.

An Eddy current separator respond to the problem of separating nonferrous metals from the remainder of refuse and depend on the ability of metals to conduct electrical current. If the magnetic induction in a material changes with time, a voltage is generated in that material, and the induced voltage will produce a current, called an eddy current. this magnetic field, induced currents flow in the metal, causing thermal loss and resulting in the reduction or stopping of oscillations. This change in state is detected by an oscillation state sensing circuit which then operates the output circuit. High-frequency magnetic field Detection coil Eddy current Eddy currents generate energy (thermal) An eddy current brake consists of a conductive piece of metal, either a straight bar or a disk, which moves through the magnetic field of a magnet, either a permanent magnet or an electromagnet. When it moves past the stationary magnet , the magnet exerts a drag force on the metal which opposes its motion, due to circular electric currents ...
