... An electromagnetic wave (such as a radio wave) propagates outwards from the source (an antenna, perhaps) at the speed of light. What this means in practice is that the source has created oscillating electric and magnetic fields, perpendicular to each other, that travel away from the source. The E an ...

... Answers: positive (to the right). When the E-field is up, the proton feels an upward force (FE = qE) and begins moving upward. Once it starts moving, it feels a force due to the Bfield. If velocity is up, and B is out of the page, the right-hand-rule gives a force, due to the B-field, to the right. ...
