A circular loop of area `1 cm^(2)` carrying a current of `10A` is placed in a magnetic field of `2That(i)`. The loop is in `xy` plane with current in clockwise direction . Fing the torque on the loop

Explanation

`vec tau = vecM xx vecB = ("ni" vecA xx vecB)`
` = [10 xx 10^(-4) (-hatk) ] xx (2 hatj) = 2 xx 10^(-3) Nm (hati) `
