# Electromagnetism, find magnitude and direction of the resulting force on wire.

1. Oct 12, 2009

A long straight horizontal wire carries a current of 70 amperes towards the east. The wire is placed in a uniform magnetic field of intensity 0.15 T towards the north.

Find the magnitude and direction of the resulting force on a 25m length of this wire

F=ILB sin $$\theta$$

F = 70*25*0.15sin 90

F = 262.5 N towards the right
