If the cross-sectional area of a magnetic field increases, but the flux remains the same, the flux density
A. increases
B. decreases
C. remains the same
D. doubles
Explanatory answer : B
Flux density = flux / area
So if area increases, flux density decreases.
A. increases
B. decreases
C. remains the same
D. doubles
Explanatory answer : B
Flux density = flux / area
So if area increases, flux density decreases.
