21. A princess refuses to remove her metal tiara as she has a MRI done, and is moved into a 3.50T field with her head point directly into the field. a. Find the average emf induced in the 20cm diameter tiara, the current induced, the power dissipated, and the magnetic field induced if it takes 3s for her to move into the field and the tiara has 0.02092 of resistance. b. How would the direction of the induced field compare...
To leam about self-inductance from the example of a long solenoid.
Learning Goal:To leam about self-inductance from the example of a long solenoid.To explain self-inductance, it is helpful to consider the specific example of a long solervid, as shown in the figure. This solenoid has only one winding, and so the EMF induced by its changing current appoars across the solenoid itsel. This contrasts with mutual inductance, where this voltege appears across a second coil wound on the same cylincter as the lirst.Part ASuppose that the current in the solenoid is...
