Ametallic laboratory spring is typically 5.00 cm long and 0.150 cm in diameter and has 50 coils.

if you connect such a spring in an electric circuit, how much self-inductance must you include for it if you model it as an ideal solenoid?
express your answer to three significant figures and include the appropriate units.

We will use a video to study faraday’s law of electromagnetic induction by analyzing the induction that occurs due a coil of copper wire sliding along an air track that passes through an external magnetic field. specifically, we will: examine some of the main principles behind faraday’s law. apply lenz’s law to determine the direction of the induced emf. take measurements of the induced emf from the voltmeter as the coil passes into and out of the external magnetic field. use the horizontal scale provided to determine the speed of the coil. calculate the magnetic field induced in the coil as it passes into and out of the external magnetic field.
