Question 110

A conductor of axial length 30 cms carries a current of 100 A and lies at right angle to a magnetic field of strength 0.4 tesla. What is the force exerted on it ?

Solution

Force acting on conductor in magnetic field is given by-

F = IlB$$\sin\theta$$

where

I = Current

l = Length of wire

B = strength of magnetic field

F = 100 $$\times$$ 0.3 $$\times$$ 0.4 $$\times$$ $$\sin 90\degree$$

F = 12 N

Therefore, force acting on current carrying conductor in given magnetic field is 12 N.

So, the answer would be option b)12 N.
