Hi guys, I'm trying to capture the electric field of a point in my 3D model of the cable by comsol 3.5a with matlab. In 2D model, I can just click the point on the model and get the result at the bottom of the screen of just put the code E = postinterp(fem,'Ez_emqvw',[0...
The present invention relates to an electro-physiologic contrast composition for magnetic particle imaging comprising electro-physiologic contrast particles that are capable of inducing anisotropic electric conductivity in the examination area and that comprise one or more magnetic particles. Further, the ...
1. there is a great documentation in comsol's software. You can find the answer of my questions right there (in the menu, Help->documentation) 2. In order to see the current flowing, you need to use Electric Currents interface in ACDC module. You can give DC voltage as choosing an e...

Assuming that you want to plot the magnitude of the z component of the electric field in a 2D space specified by the variables“x” and “y” and all the data is in the form of arrays, you can use the “imagesc” function. To use the fun...
Capacitively Coupled (CCoupled) electric fields are used to stimulate cell cultures in Tissue Engineering. Knowing the electric field (E-Field) magnitude in the culture medium is fundamental to establish a relationship between stimulus strength and cellu
How is the direction of an electric field defined? A field is not a vector, so it does not have a direction. The direction of the field is the direction of the force on a neutron. The direction of the field is the direction of the forc...
Let's find out. Circuit Breaker: At Work in Your Home This diagram shows the basic parts and design of a circuit breaker. HowStuffWorks The power distribution grid delivers electricity from a power plant to your house. Inside your house, the electric charge moves in a large circuit, ...
Electric Field Formula Now we can measure the field. The electric field generated by a charged object, is in fact the electric force between the object and the test charge, divided by the magnitude of that test charge. Coulomb’s Law will help us find the force. ...
