Why is the Lorentz force calculated in Ansys Maxwell so low?

AI Thread Summary
The Lorentz force calculated in Ansys Maxwell appears significantly lower than expected, with results around 10^-4 N compared to the anticipated 0.1 N based on the formula F=B*I*l. The model involves a magnetically conductive plate in a static magnetic field, which should enhance the magnetic field strength to approximately 10 mT. Despite using both 3D and 2D models, the results remain consistent and unexpectedly low. The discussion highlights a potential misunderstanding or missing factor in the calculations or model setup. Further investigation or sharing of the project file may be necessary to resolve the issue.

Why is the Lorentz force calculated in Ansys so low? According to the formula F=B*I*l, it is supposed to be at least 1000 times higher. The model is really simple: a magnetically conductive plate in a static magnetic field inducts the magnetic field from the surrounding space, which makes its own magnetic field dozens of times stronger than in the surrounding vacuum (which is perfectly logical) - around 10 mT. A 10 A electric current runs perpendicular to this magnetic field in the plate. According to the formula, F=B*I*l=10-2*10*1=0.1 N, but the program produces results in the range of 10-4 N for the Lorentz force. I have tried both 3D and 2D models and the result is nearly identical. What am I missing?

p.s. I can attach my project file if it helps

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
