### Circuit Capability in MagNet for SOLIDWORKS

Electromagnetic devices are widely used across most industrial applications to strategically to do some form of work. Efficient use of these devices requires that they be influenced with a desired excitation. Most often the generation of this excitation requires the use of a circuit to control the specific characteristics, timing and overall profile.

### Eddy Current NDT and Deep Flaws (T.E.A.M. Problem 27)

In this example, a sheet of aluminum contains a screw hole with a flaw inside. The flaw is to be detected using the eddy current method. A coil is stationary above the screw hole, which generates eddy currents inside of the aluminum. Two diametrically opposed Hall effect sensors measure the horizontal differential flux density at the surface of the screw hole.

### Slot Configurations for Reducing Stray Losses (T.E.A.M. Problem 21a)

This example involves four different configurations of shielding steel plate: a plate with no slots, one slot, two slots, and three slots. The magnetic field density is measured along contours on the surface of the plate, and compared with measured results.

### Impact of Materials on Reducing Stray Losses (T.E.A.M. Problem 21b)

This examples involves three different configurations of plates: one magnetic and one non-magnetic plate, two magnetic plates and two non-magnetic plates. The flux density is measured along contours on the plates’ surface and compared with measured results.

### Impact of Shield Thickness on Reducing Stray Losses (T.E.A.M. Problem 21c)

There are two types of shields in this benchmark: one single silicon steel sheet or copper plate (M1 or EM1), or three separated silicon steel sheets or plates M2 or EM2). The transformer wall is made out of magnetic steel.

### Rectangular Slot in a Thick Plate: a Problem in Non-destructive Evaluation (T.E.A.M. Problem 15)

In order to detect flaws, sensor problems require the accurate calculation of induced eddy currents. MagNet for SOLIDWORKS AC Time Harmonic solver automatically calculates these eddy currents. The results presented compare published experimental data demonstrating the accuracy of the software.

### 3-D Static Force Benchmark (T.E.A.M. Problem 20)

This rig is made from a steel center pole and yoke. The center pole is surrounded by a copper coil excited by a DC current. This problem shows the ability of MagNet for SOLIDWORKS to solve Static Magnetic Problem involving force and magnetic field calculations.

### Nonlinear Time-Transient in Switched Reluctance Motors (T.E.A.M. Problem 24)

This is a test rig configuration similar to a switched reluctance machine. It is made of solid medium-carbon steel and mounted in a nonmagnetic cage which can rotate about a stainless steel shaft. This is a nonlinear transient problem, which was simulated using MagNet for SOLIDWORKS transient solver.
