Question

A.What are the direction of the magnetic force on a 1.00

cm section of this wire if the magnetic-field direction is toward the east?

B. What are the magnitude of the magnetic force on a 1.00

cm section of this wire if the magnetic-field direction is toward the east?

C. What are the direction of the magnetic force on a 1.00

cm section of this wire if the magnetic-field direction is toward the south?

D. What are the magnitude of the magnetic force on a 1.00

cm section of this wire if the magnetic-field direction is toward the south?

Explanation / Answer

A

Current = I = 1.30 A ( downward )

Magnetic field = B = ?( horizontal) (assume 0.562 T )

Wire length = L = 1.00 cm =0.01 m

Angle between wire length and magnetic field = thetqa = 90 degree

Magnitude of the magnetic force = F = BIL sin theta

F =0.562*1.30*0.01*sin 90

Magnitude of the magnetic force=F =0.007306N

The direction of force is horizontal,31 degree toword east.
