Options
A) 0.46N
B) 0.35N
C) 0.36N
D) 0,24N
The correct answer is C.
Explanation:
F = BIL = 0.4 x 6 x \(\frac{15}{100}\)
= 0.36N

F = BIL = 0.4 x 6 x \(\frac{15}{100}\)
= 0.36N
wat is the meaning of BIL
F = B I L
F is force measured in newtons (N)
B is flux density (the strength of a magnetic field I.e No. of magnetic lines of force from magnet per unit area) measured in teslas (T, named after Nikola Tesla)
I is current measured in amperes (A)
L is the length of conductor in the magnetic field measured in metres (m)
