Question

The magnetic flux through each of five faces of a die (singular of ''dice'') is given by ΦB = ±N Wb, where N (= 1 to 5) is the number of spots on the face. The flux is positive (outward) for N even and negative (inward) for N odd. What is the flux through the sixth face of the die?

Answer 1

Answer:

Ф6 = 3 Wb

Explanation:

the flux is positive when N is odd and positive when N is even so we can write the flux through the all side as

∑ N=1, to5

∑ -1 ^N Ф N * Ф6 =0

∑ -1 ^ N * Ф6 =0

Where :

ФN=N

Replacing and operated so  

-1 Wb +2 Wb - 3 Wb + 4Wb - 5Wb + Ф6=0

Ф6 - 3Wb = 0

Ф6 = 3 Wb
