## What are the achievements of James Clerk Maxwell?

• Maxwell is best known for his research in electromagnetic radiation, which unites the sciences of electricity, magnetism and optics.
• In 1856, aged 25, Maxwell began work on another field of research – the composition of the rings of Saturn.

### What is the significant contributions of James Clerk Maxwell in the development of electromagnetic wave theory?

Maxwell and Hertz. About 150 years ago, James Clerk Maxwell, an English scientist, developed a scientific theory to explain electromagnetic waves. He noticed that electrical fields and magnetic fields can couple together to form electromagnetic waves.

What are the two Maxwell’s equations for magnetostatic fields?

Generally, the magnetic field in the presence of a current density J is given by Maxwell’s equation (2): ∇ × H = J.

What is the triangle in Maxwell’s equations?

The triangle and dot symbol in front of the field symbols (called the “divergence” operator) is a mathematical way to measure if a field behaves as a source or a sink at a specific point in space.

## What is an upside-down triangle in physics?

Partial derivative operator, nabla, upside-down triangle, is a symbol for taking the gradient, which was explained in the video. Sidenote: (Sometimes the word “operator” is interchangeable with “operation”, but you see this all the time.

### What is the triangle called in physics?
