Question

Based on the definition of the magnetic flux, which of the following will without a doubt increase the magnetic flux? (select all that apply)

Obtaining a larger diameter coil while holding   and B constant

Changing   in a constant B-field and constant A such that instead of

Changing in a constant B-field and constant A such that instead of

Changing in a constant B-field and constant A such that instead of

Reducing B while increasing A and keeping   a constant

Obtaining a smaller diameter coil while holding   and B constant

Explanation / Answer

phi = BA*costheta

if we increase diameter , means area will increase , so phi will increase

theta = 90 menas cos90 =0

theta = 0 cos0 = 1
