6. How can a motion of a charged particle be used to distinguish between a magnetic field and an electric field in a certain region (A) The charged particle always follows a spiral path in an electric field. (B) The charged particle always follows a linear path in magnetic field. a (C)The charged particle follows a spiral path in a magnetic field. (D) It is impossible because the charged particle with have identical paths in both fields 7. A bar magnet is stationary while a of wire is was moved toward the magnet at constant velocity as shown in Figure the direction of the induced current in the loop while from moving toward magnet (State the directions a if you were the right of the magnet, watching the loop of wire move away igure 4 no current is

Explanation / Answer

ans 6 )

F = q(vxB)

F = qE

magnetic force is always perpendicular to magnetic field

the charged particle always follow a linear path in magnetic field .

Ans 7 )

direction is anti-clock wise
