Question

Which of the following statements are true? Choose all that apply.

1. Magnetic fields deflect moving charges.

2. The magnetic force is always perpendicular to both the magnetic field and the velocity of the charge.

3. Magnetic fields don't do any work on charges.

4. Magnetic fields are created by moving charges.

5. The magnetic field is always perpendicular to the velocity of the charge.

6. Magnetic fields cause charges to speed up.

Explanation / Answer

F = q(vxB); cross product => magnetic force is perpendicular to both the magnetic field and the velocity of the charge. Magnetic field deflects charges and hence they move out of their course in a magnetic field. Magnetic fields deflect charges and doesnt change their speeds. yes,magnetic fields are creates by charges moving with uniform speed.
