Magnetic flux density
Understand the Problem
The question asks for the definition or meaning of magnetic flux density, a fundamental concept in electromagnetism that describes the strength and direction of a magnetic field.
Answer
Magnetic flux density (B) measures the strength of a magnetic field, quantified as force per unit current per unit length, and is measured in Tesla (T).
Magnetic flux density, denoted as B, measures the strength of a magnetic field. It can be defined as the force acting per unit current per unit length on a wire placed at right angles to the magnetic field. It is measured in Tesla (T).
Answer for screen readers
Magnetic flux density, denoted as B, measures the strength of a magnetic field. It can be defined as the force acting per unit current per unit length on a wire placed at right angles to the magnetic field. It is measured in Tesla (T).
More Information
The terms magnetic flux density, magnetic induction and magnetic field strength are often used interchangeably. The symbol B is used to represent magnetic flux density.
Tips
Confusing magnetic flux density with magnetic flux is a common mistake. Magnetic flux is the measure of the total magnetic field that passes through a given area, while magnetic flux density is a measure of the strength of the magnetic field at a point.
