Consider the example of a permanent magnet (B-field pointing upward, so N on top and S on bottom) falling through a long metal pipe. You have picked a spot in the middle of the pipe and the magnet is already below it and falling away. What is the induced current in the pipe and the resulting magnetic field. Explain completely.
Homework Answers
as the magnet falls , the magnetic flux through the pipe decreases. so to increase the magnetic flux in upward direction , the pipe induces current so as to have its own magnetic field in up direction . for the magnetic feild to be in up direction, the induced current must be counterclockwise as seen from above

Here's a cool example: Permanent magnets. If B are produced by currents, then what's up with permanent magnets? You don't have to plug them in, they just work. What's the current? One idea is that it could be the e' orbiting the nucleus. A charge moving in a circular loop is a sort of current. (You'll calculate this in Problem 30.6) Let's estimate the speed of the e' using Newton's Laws: the only force is the Coulombo attraction, and we'll...

Magnetism 1. (4) An unknown particle travelling at a velocity of 2.20x106 m/s to the right as seen by an observer, enters a region that has an electric field of magnitude 750 V/m pointed away from the observer. Ignore gravity for this question. (a) What is the direction and magnitude of the perpendicular magnetic field which would best cancel out the effect of the electric field so that the particle passes through undeflected? (b) If while travelling 0.200 m, with...
To leam about self-inductance from the example of a long solenoid.
Learning Goal:To leam about self-inductance from the example of a long solenoid.To explain self-inductance, it is helpful to consider the specific example of a long solervid, as shown in the figure. This solenoid has only one winding, and so the EMF induced by its changing current appoars across the solenoid itsel. This contrasts with mutual inductance, where this voltege appears across a second coil wound on the same cylincter as the lirst.Part ASuppose that the current in the solenoid is...
