Question

Correct expression for force on a current carrying conductor of length dl in a magnetic field is ______.

पर्याय

• `vec"F" = 2"I"vec"d"l xx vec"B"`

• `vec"F" = "I"vec"d"l xx 2vec"B"`

• `vec"F" = epsilon_0"I"(vec"d"l xx vec"B")`

• `vec"F" = "I"(vec"d"l xx vec"B")`

Answer 1

Correct expression for force on a current carrying conductor of length dl in a magnetic field is `underline(vec"F" = "I"(vec"d"l xx vec"B"))`.

Explanation:

Force experienced by a conductor of length dl carrying current I placed in magnetic field B is given by `"I"(vec"d"l xx vec"B")`.
