Question

A circular loop of radius 5 cm carries a current of 5A, it has a uniform magnetic field of 2,0T. Calculate the magnetic force on the loop.

Answer 1

`F = BIl`

F » magnetic force

B » magnetic flux density

l » length / circumference

`F = BI(2\pi r)`

r » radius

`F = 2 * 5 * (2 * 3.14 * 0.05) \\ { \underline{force = 3.14 \: \: newtons}}`
