Zayra runs electric current through 38 coils of wire in a series circuit and measures a magnetic field strength of 79.3 µT around the coils. She then inserts a ferromagnetic core inside the coils to create an electromagnet and measures the magnetic field strength again. Which of the following answers would be a correct measurement

One form of energy can be another type of energy. a. created to form b. transformed into c. destroyed and then created to form

Which of these is constant for all types of electromagnetic radiation in a vacuum? select one: a. wavelength b. frequency c. photon energy d. amplitude e. velocity

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.
