A solenoid made of magnet wire (#20 gauge) with 12.3 turns per cm is attached to a 536 Ω resistor and a 110 V DC source. The diameter of the solenoid is 1.8 cm and its length is 15 cm a. (5 points) What is the self-inductance of the solenoid? b. (5 points) The emf induced in the solenoid depends on a changing current. After a long time the current will stop changing, and the only voltage drop in the...

Moving charges will produce a local magnetic field, but the reverse is also true a changing magnetic field will similarly induce charges to move (ie. produce current). Consider a magnet moving into a coil of wire: A spinal coil of wire with many closely-spaced tums this is called a solenoid is connected to a micro-ammeter as shown in the diagram above. As the magnet moves into the coil, any induced current will be measured by the micro-ammeter. Question On the...
A conducting rod is being dragged along conducting rails, as shown in (Figure 1)
Part A A conducting rod is being dragged along conducting rails, as shown in (Figure 1). The magnetic field is directed out of the screen. In what direction does the induced current flow through the light bulb? There is no induced current. The induced current flows through the bulb from the left to the right. The induced current flows through the bulb from the right to the left. Part B A circular loop of conducting wire is moving through a uniform magnetic field, as...
