Discuss Lenz's Law in terms of Faraday's Law and induced current (Requires website source)

Expert Solution

Faraday's law: induced electrical current = (change in magnetic flux) / (change in time) / (total electrical resistance)

Faraday's law says that, not only do changes in position and current INDUCE other currents and magnetic field, but also their strengths depend also on the speed this was done. The idea here is that, if you CUT as much of the magnetic field as possible in as little time as possible, a current of specific strength is INDUCED. This often depends on the force you do use to accomplish this. In other words, the NEW current you create comes from the opposition (Lenz's law) to the force you supply as quickly as you can (Faraday's law = Lorentz law in reverse). This uses the same "right-hand-finger" convention mentioned earlier for the Lorentz Deflection, only here, you are "solving" for the INDUCED current instead of the deflection force. However, remember that even here, the RIGHT INDEX finger still points the direction of the induced current, and the RIGHT THUMB still points in the direction of the supplied force.

These questions are about Faraday's Law and Lenz's Law (DC circuit) 1. Why is the magnitude of the induced current larger when a magnet or some other primary source moves to the coil fast? 2. Does a higher EMF (voltage) increase or decrease induced current? What about the opposite? 3. How does the number of loops affect induced current? Does a higher area of a loop increase induced current? 4. What source of energy causes induced current?

Topic: Magnetism and electromagnetic induction, faraday's law, lenz's law Question: A magnet is held a little above the top of a coil. It is then dropped into and through the loop, north side facing down, and caught as it exits the loop. Assuming the magnet never touched the loop (zero friction), would its velocity after falling through the loop be greater, smaller, or the same as if it had been dropped freely (not through the loop)? Explain your answer using...

Faraday's Law: What would you observe about the amplitude of an induced signal as the frequency varied? Describe whether the behavior is consistenent with Eq. 3 (Vo= w(Nd)A(Bo)cos(theta)). In particular what should your graph of amplitudes against frequencies look like according to Eq 3? In comparisons with the predictions of Eq 3, why would it be important to adjust the function generator to keep the amplitude of the B field the same at each frequency?
