... (and hence v) is negative, yet the force must be acting in a downward direction. Therefore, the “-” must be part of the force to make sure that, overall, the force is positive and hence acting in the downward direction. Likewise, when the mass is moving downward the velocity (and so v) is positive. ...

... In the 1830’s, Michael Faraday created an apparatus in which an insulated wire is wrapped around a ring. The ring was also attached to a galvanometer, which measures very small current. Faraday noticed that a constant current did not produce a current in the galvanometer. But at the instant he turn ...

... placed near a magnet, it will be attracted toward the region of greater magnetic field. This is what we are most familiar with when our magnet picks up a bunch of paperclips. Iron, cobalt, nickel, gadolinium, dysprosium and alloys containing these elements exhibit ferromagnetism because of the way t ...

... These expressions have been derived in the near field limit (r << l). Let’s notice that they are exactly the same expressions known for the fields due to static electric and magnetic dipoles. So if we calculate the Poynting vector of these fields we obtain exactly zero because they don’t carry out e ...
