### Simulator for trajectories of charged particles in electric fields?

You may have a look at agros2d which could simulate electrostatic fields determined by various boundary conditions and then charged particles in the electric field. A similar case as you mentioned in ...

### Simulator for trajectories of charged particles in electric fields?

Simion Directly from the product website: SIMION is a software package primarily used to calculate electric fields and the trajectories of charged particles in those fields when given a ...

### Contravariance and covariance of vectors

That's because you're using the 'fake' version of gradient. The true version for a scalar field $F$ is given as: $$(\nabla F)= \frac{\partial F}{\partial Z^i } e^i$$ Here $e^i$ is the dual basis and ...

### Is Farady's law valid for conducting loop only?

Faraday's law is for a mathematical loop, even with nothing there.

### What happens inside a conducting wire if it is placed in an electric field?

If the field is static, the conductor will be equipotential in the equilibrium state. If you bring the conductor in the field from a region with no field or with a different value of the field there ...

### Why Does an Electric Field Arise In This Situation?

The problem lies in the measurement method, not in the medium itself. As soon as you connect the battery, you will always have an electric field (actually also if you do not connect the battery), no ...

### What is the electric field and potential inside and outside grounded conducting and non grounded conducting sphere?

The conducting sphere is a Faraday cage: The field inside it is zero. What does the grounding do for that? Nothing! Remember that the electric field is the gradient of the potential and does not ...

### What would be the outcomes in this arrangement? would potential varies along a conducting wire?

Assuming the the sphere separation is large enough that the surface charge densities remain spherical, and assuming that charges from the wire do not significantly change that distribution, then ...
