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

[RaDitZ]

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

Is it the right answer?

 

[rl.bhat]

The force should be perpendicular to east and north. Using Flemming's left hand rule find the direction.
