Magnetism and Magnetic Forces — Homework
Check whether the velocity or current is perpendicular to the field before dropping the sin(theta) factor.
- 1.A charge of 5x10^-6 C moves at 2x10^5 m/s perpendicular to a 0.8 T field. Find the force on it.
- 2.A 0.5 m wire carries 10 A perpendicular to a 0.4 T field. Find the force on the wire.
- 3.Explain why breaking a bar magnet in half does not produce a separate north pole and south pole, but instead two smaller complete magnets.
- 4.Explain why the magnetic force on a moving charge is maximized when the charge moves perpendicular to the field and zero when it moves parallel to the field.
- 5.Describe the compass-and-magnet (or compass-and-wire) lab and explain what it demonstrated about magnetic fields or the connection between electricity and magnetism.
