Maxwell Stress Tensor Force Calculation

Expert Guide to Maxwell Stress Tensor Force Calculation

Introduction & Importance

Maxwell stress tensor is a crucial concept in electromagnetism, describing the force per unit area exerted by an electromagnetic field on a surface. Understanding and calculating this force is vital in various applications, from antenna design to plasma physics.

How to Use This Calculator

1. Enter the electric field components (E1, E2, E3) in volts per meter (V/m).
2. Enter the permeability of free space (mu0) in henries per meter (H/m).
3. Click ‘Calculate’.

Formula & Methodology

The Maxwell stress tensor (T) is given by:

T = ε₀ * E * E – μ₀⁻¹ * H * H + (ε₀ * E * H) / 2

Where E is the electric field, H is the magnetic field, ε₀ is the permittivity of free space, and μ₀ is the permeability of free space.
