Question

Which of these will experience a magnetic force in a magnetic field? Check all that apply a positive or negative charge at rest a moving charge moving parallel to the field a moving charge moving to the field Which of the following cannot induce a voltage in a loop of wire? Expanding or contracting the loop in a region where there is no magnetic field. Moving the loop near a magnet. Moving a magnet near the loop Changing the current in a nearby loop. A particle with a charge of 0.06 C is moving at right angles to a uniform magnetic field with a strength of 05 T. The velocity of the charge is 600 m/s What is the magnitude of the force exerted on the particle?

Explanation / Answer

a moving charge moving perpendicular to the field.

----------------------

Expanding or contracting the loop in a region where there is no magnetic field.

9. F = q ( v x B) = q v B sin(theta)

F = 0.06 x 600 x 0.5 x sin90

F = 18 N
