3d Magnetic Field Simulator Free 8/27/2019 Overview: SIMION Version 8.1 is a software package primarily used to calculate electric fields and the trajectories of charged particles in those fields when given a configuration of electrodes with voltages and particle initial conditions, including optional RF (quasistatic), magnetic field,. Magnetic simulation, as magnetics, transient magnetics, magnetostatics, finite element simulation. Magnetic simulation usually is the same as a low frequency electromagnetic simulation based on magnetic field only, without the electric part of electromagnetic field taken into account. Magnetic simulations are often divided into AC Magnetics, DC. EMS is a 3D electromagnetic field simulator software suite, based on the powerful finite element method. Currently, it is the only electromagnetic Add-in available to SOLIDWORKS users. EMS is Gold Certified by SolidWorks® and targets four main areas: electromechanical, electromagnetic, power electronics, and electromagnetic behavior.
The MLX90395 is a 3D magnetometer capable of measuring X, Y, and Z magnetic fields and is an expansion of the set of Melexis sensors offering this output. Unlike many other magnetometers, the MLX90395 is designed to sense magnetic fields produced by a permanent magnet versus earths magnetic field. Therefore, the MLX90395 is well suited to sense the position of a static or moving magnet in the vicinity of the sensor by measuring the magnetic fields produced by it.
Compared to the previously released, consumer-product-focused MLX90393, the MLX90395 shares many features but also differs in many ways.
Wider temperature range
The MLX90395 operates over a wider temperature range than the MLX90393, from -40 degC to 125 degC ambient, making the MLX90395 suitable for in-cabin, on-body, or light powertrain applications in automotive. It is also suitable for many industrial applications like factory automation, robotics, or material handling.
Higher speed operation
The speed has been increased, up to a 2kHz peak sampling rate, when measuring all three magnetic field axes.

Supply voltage measurement
The MLX90395 can also measure its own supply voltage to enable a plausibility check to be conducted with the ADC in the host microcontroller. The supply voltage measurement also enables monitoring of battery discharge in battery powered applications.
Two ranges of field
The MLX90395 provides two magnetic field versions; a medium field and a high field version. The medium field version enables 50mT maximum magnetic field in the X and Y axes and 130mT in the Z axis. The high field variant extends the magnetic field range to 120mT in the X and Y axes with the same 130mT maximum field in the Z axis.The high field version is particularly suited for applications where stray magnetic fields, produced by another magnet or by a current carrying conductor, may be present. By increasing the desired signal from the permanent magnet the error due to the infringing field will be reduced.For both versions, exceeding the maximum field range will not damage the sensor. Returning within the operating conditions will return the sensor to normal operation.
Automotive qualification and multi-packages
Finally, the MLX90395 is automotive qualified to the AEC Q100 standard and is available in a RoHS compliant 3x3mm QFN16, SOIC8, or TSSOP16 package. The QFN16 and SOIC8 packages contain a single silicon die while the TSSOP16 contains two fully independent dies for applications requiring redundancy for safety or availability reasons.
Protocol
The MLX90395's output is selectable between SPI or I2C allowing flexibility in integration. The SPI protocol operates at a clock speed up to 10 megahertz while the I2C protocol supports I2C standard mode with clock rates up to 100 kilohertz or I2C fast mode with clock rates up to 1 megahertz. Trigger and interrupt pins are provided for starting measurements at defined times and flagging when data is ready. Triggering via command and polling are also supported for pin-count constrained applications.

Flexibility
The MLX90395 is highly configurable. For example, the axes to be converted can be chosen from any combination of X, Y, and Z. For example, in many rotary motion applications only X and Y magnetic fields need to be sensed. The Z axis can therefore be skipped saving current and time. The supply voltage and temperature measurements are similarly selectable.
