The strength of a magnetic field is called?
Correct answer: C. Magnetic flux density
- A. Strength
- B. Flux
- C. Magnetic flux density
- D. Density
Explanation
.Option A) Strength is not correct because it is a general term and does not specifically refer to the strength of a magnetic field.Option B) Flux is not correct because it refers to the total amount of magnetic field passing through a given area, which depends on both the strength and the size of the magnetic field.Option C) Magnetic flux density (B) is defined as the force acting per unit current per unit length on a wire placed at right angles to the magnetic field. Magnetic field strength is also called Magnetic Intensity or Magnetic Field Intensity or Magnetic Field Strength. Option D) Density is not correct because it is a general term that refers to the amount of a substance or quantity per unit volume or area and does not specifically refer to the strength of a magnetic field.

About Magnetic Flux Density
Magnetic flux density measures the magnetic force acting on a current carrying conductor or moving charge in a magnetic field. Work includes the relations B equals F divided by IL and F equals qvB, the tesla as its SI unit, field direction and the distinction between flux density and magnetic flux.
