... a. The direction of the tangent to a field line is the direction of the electric field E at that point b. The number of field lines per unit area is proportional to the magnitude of E: the more field lines the stronger E • Electric field lines point in direction of force on a positive test charge th ...

... The long solenoid S shown (in cross section) in Fig. 30-3 has 220 turns/cm and carries a current i=1.5 A ; its diameter D is 3.2 cm. At its center we place a 130-turn closely packed coil C of diameter d=2.1 cm. The current in the solenoid is reduced to zero at a steady rate in 25 ms. What is the mag ...

... As the electromagnetic wave moves rightward past the rectangle, the magnetic flux B through the rectangle changes and— according to Faraday’s law of induction— induced electric fields appear throughout the region of the rectangle. We take E and E + dE to be the induced fields along the two long side ...

Key HW 7_3.
... The fact that the magnet falls so slowly and not really accelerates implies that in addition to the gravity force another force is acting on the magnet that will cancel out the gravity force. This other force is the magnetic force. The falling magnet will cause flux changes in the copper pipe, resul ...
