## How is magnetic dipole moment measured?

The magnetic dipole moment of a substance (how well it acts as a magnet) can be determined by suspending a sample of the substance on a torsion fiber and measuring the period of the oscillations of the sample in an applied magnetic field. The larger the magnetic dipole moment, the faster the oscillation.

## Why a magnet is called a magnetic dipole?

Answer. Answer: A magnet is called a “magnetic dipole” because it has two poles (north and south).

## What is called electric dipole?

What is Electric Dipole? An electric dipole is defined as a couple of opposite charges “q” and “–q” separated by a distance “d”. By default, the direction of electric dipoles in space is always from negative charge “-q” to positive charge “q”. The midpoint “q” and “–q” is called the centre of the dipole.
