F=BIL Or is it….. F=qvB

V B

The force is to the left.

V B

The force is out of the plane of the page.

B I

The force is to the left.

F = 1.5x10-12 N V = 2.0x107 m/s Electron B = ?

The magnetic field is directed toward the bottom of the page.

B = .15 T Electron V = 1.5x106 m/s F = ?

No force exists as B and v are anti-parallel.

B = .75 T What is the direction in which the proton will accelerate? V = 5.8x106m/s

The proton accelerates toward the bottom of the page The proton accelerates toward the bottom of the page. The force is perpendicular to the velocity of the proton, so it causes the proton to change direction; although it will not speed up or slow down the proton.
