1

The electric force is directed along...

E

2

The electric force acts on...

moving and stationary charges

3

What type of work can the electric force do?

non zero work

4

Distinctions between E and B

1. The Magnetic force is perpendicular to B
2. The Magnetic force acts on moving charges only.
3. The Magnetic force does no work (no V).

5

For a moving charge in a magnetic field, Fb is proportional to:

q0, v, B

6

Fb is perpendicular to...

both v and B

7

Is cross product commutative?

No

8

Magnetic fields cannot do this. what good is it then?

Cannot change kinetic energy. Magnets deflect.

9

Relationship between magnetic field direction and field lines

Field direction is tangent to magnetic field lines at any point.

10

magnetic field form

closed loops

11

Magnet shapes

Bar, Horseshoe, C magnet

12

Compass points in what direction?

South pole of magnetic field.

13

Torque

A measure of a force's ability to induce angular acceleration.

14

radial acceleration =

v^2/r
