Please help with Induction!!! A 0.5m diameter aluminium plate moves downward at 0.1m/s along the axis of a 1m long solenoid proving a magnetic field of 3T at the centre. The plate moves from position 1m above the solenoid and move down to a position 1m below the solenoid. The way it moves is described in the attachment Solenoid.jpg. First of all is it even possible to find the induced emf in the plate without some really complex (and by complex i mean beyond 2nd year university level) ?? BEcause every question asks for sketch i am guessing that i don't need numbers involved in this Now onto the quesitons themselves Sketch a graph of the magnetic field along the path of the plate. I would guess that the magnetic field is a constant value all along the length of the solenoid and then falls off exponentially at points beyond that Sketch a graph of the EMF induced in the plate as a function of vertical position The EMF would be constantly increasing positively as the plate approaches the solenoid from the top, and then while in the solenoid, the emf would be increasing as well and then go to new negative minimum after the plate passed the mid point of the solenoid and then gradually increase? Sketch how the current flows in the plate. Eddy currents are the currents within the plate, yes? SO the currents would be circulating parallel to it's circumference? Sketch a graph of the induced magnetic field from the plate Not sure but the magnetic field would eventually increase as the induced EMF increased and as a result the induced B would be increasing and then falling off in the same way the solenoids magnetic field fell off? Sketch a graph of the force on the plate. F = qvBsin(theta) SO the force is constantly increasing as the plate moves closer to the solenoid. Please check my answers i am not sure about some of them. Your help would be greatly appreciated!
