Use Ampere's Law to derive that inside a wire with a uniform current distribution, B(r) is proportional to r. Recall the case of the electric field E(r) inside a wire with a uniform charge distribution: E(r) is also proportional to r. Outside a long, straight wire, both E and B as proportional to 1/r. Transcribed image text: In the solenoid shown in the diagram, which position indicates the direction of the magnetic field at the center of the solenoid? current direction left down right up The current illustrated in the diagram is directed upward in a straight vertical wire. A compass is placed alongside the wire at the X mark. Which way will the compass point? north west south east south ... Lenz’s Law. The direction of the induced emf drives current around a wire loop to always oppose the change in magnetic flux that causes the emf. Lenz’s law can also be considered in terms of conservation of energy. If pushing a magnet into a coil causes current, the energy in that current must have come from somewhere.
