What is the definition of magnetic flux?.
- A.The product of magnetic field strength and area perpendicular to the field
- B.The total magnetic field strength in a given area
- C.The force experienced by a current-carrying conductor in a magnetic field
- D.The rate of change of magnetic field strength over time
Model answer
What a good answer should say
- The product of magnetic field strength and area perpendicular to the field
Explanation
Why this works
Magnetic flux is defined as the product of the magnetic flux density (B) and the area (A) through which it passes, specifically when the area is perpendicular to the field. This is given by the formula Φ = B × A.
