Question

if we double all the parameters of force acting on current carrying conductor placed inside uniform magnetic field keeping the conductor perpendicular to field then magnetic force become:
with solution
​

Answer 1

Answer:

) (a) When current carrying conductor is placed parallel to magnetic field, magnitude of force is zero. (ii) Fleming's left hand rule: Stretch the thumb, fore finger and middle finger of left hand such that they are mutually perpendicular.

Answer 2

Answer:

8 times

Explanation:

you have to double all the parameters of force so,

F=ILBsin0

there are 4 parameters for force

thus,

4 x 2 (because we have to double)

the ans = EIGHT times.
