Final answer:
When you drop a bar magnet through a copper tube, an electric current is induced in the tube, which is true due to Faraday's Law of Electromagnetic Induction and Lenz's Law causing electromagnetic damping.
Step-by-step explanation:
The initial question regarding pressing DIR sending the small fader output to the MTR seems unrelated to the physics principle involved in dropping a bar magnet through a copper tube. However, the answer to the physics question is that it is true—if you drop a bar magnet through a copper tube, it will indeed induce an electric current in the tube. This is because as the magnet falls, the magnetic field around the magnet changes relative to the position of the copper tube. According to Faraday's Law of Electromagnetic Induction, a changing magnetic field will induce a current in a conductor. In this case, the copper tube acts as the conductor. The induced current will create its own magnetic field, which will oppose the change that caused it, in accordance with Lenz's Law. This will result in a noticeable slowing of the magnet's fall, an effect often referred to as electromagnetic damping. The given statement is unclear and seems to be incomplete. The term "DIR" could refer to various things, and the context of "Small Fader Output" and "MTR" is not defined. As a result, I cannot accurately determine whether the statement is true or false. If you could provide more context or details about the terms used in the statement, I would be better able to assist you in evaluating its correctness.
