Full description

O EMax é uma caixa de ferramentas para estudantes de Engenharia Elétrica e áreas afins que estão cursando Eletromagnetismo. ÁLGEBRA VETORIAL • Soma e subtração de vetores • Produto escalar e produto vetorial • Módulo, vetor unitário e ângulo entre vetores • Projeção de um vetor sobre outro • Multiplicação por escalar CONVERSÃO DE COORDENADAS Converta pontos entre os três sistemas em qualquer direção: • Cartesianas ↔ Cilíndricas • Cartesianas ↔ Esféricas • Cilíndricas ↔ Esféricas CÁLCULOS DIFERENCIAIS AVANÇADOS • Gradiente (∇f) — calcule o gradiente de qualquer função escalar em coordenadas cartesianas, cilíndricas e esféricas • Divergente (∇·F) — fluxo líquido de campos vetoriais nos três sistemas • Rotacional (∇×F) — circulação de campos vetoriais nos três sistemas LEIS DE MAXWELL As quatro equações fundamentais do eletromagnetismo em forma diferencial e integral, com descrição física de cada uma: • Lei de Gauss para o campo elétrico • Lei de Gauss para o campo magnético • Lei de Faraday • Lei de Ampère-Maxwell

What's new

Primeira versão do EMax. • Gradiente, divergente e rotacional em coordenadas cartesianas, cilíndricas e esféricas • Operações vetoriais completas com passo a passo • Conversão entre os três sistemas de coordenadas • As quatro equações de Maxwell com referência rápida • Teclado de atalhos para escrever funções facilmente • 100% offline, sem anúncios
