Assume that the magnetic field at each point of the coil has a constant magnitude of 0.220 T and is directed at an angle of 60.0 Deg outward from the normal to the plane of the coil. Let the axis of the coil be in the y-direction. The current in the coil is in the direction ...
Current flow in a wire or other conductor produces the magnetic field. Invisible magnetic flux lines emanate from the magnet and may influence objects in or near them. An electric field derives from a voltage, or what we call a potential, across two conductors. The attraction of the positive...
This work deals with the design of coils to obtain a desired magnetic field in the axial direction. A computer program has been developed to implement the obtained equations and assist the design. Practical results are given to illustrate the accuracy of theoretical predictions with measured magnetic...
A difficult problem concerns the determination of magnetic field components within an experimentally inaccessible region when direct field measurements are not feasible. In this paper, we propose a new method of accessing magnetic field components using
I created a gauss probe with a linear hall effect, and can measure the desired levels on my PC Scope. I wound a flat circular coil, and see that the desired levels are present. The coil is wound all the way to the center. Over the center the field is quite strong, and tapers off...

A method for monitoring the misalignment of the magnetic axis in solenoids is proposed. This method requires only a few measurements of the magnetic field at fixed positions inside the magnet aperture, and thus overcomes the main drawback of sturdy moving mechanics of other Hall sensor-based metho...

where p is the electric dipole moment, which has magnitude equal to the product of one of the dipole charges and the length of the dipole, and direction pointing from the negative to the positive charge (Figure 32.22). Analogously, the torque on a magnetic dipole in a magnet field and th...
