## woleraymond 3 years ago A current of 5A is carried by a straight wire in a uniform flux density of 2 x 10^-3T. Calculate the force per unit length on the wire if it is a - Perpendicular to the field b - inclined at 30degrees to it

Use $F = B I L sin \theta$, but solve with the L on the same side so your answer will be in Newtons per length.
