Question

carl and abby are discussing what they have learned in class about electricity and magnetism. carl tells abby that an electric current running along a wire can be used to produce a magnetic force. abby, on the other hand, tells carl that moving electrons through a magnetic field can produce an electric current. which of the students is/are correct? a. both carl and abby are correct. b. only carl is correct. c. only abby is correct. d. neither student is correct.

Explanation:

Carl's statement is based on Ampere's law which shows that an electric - current in a wire creates a magnetic field, thus a magnetic force. Abby's statement is based on Faraday's law of electromagnetic induction where moving electrons (a current) in a magnetic field can induce an electric current. Both are fundamental principles in electromagnetism.

Answer:

A. Both Carl and Abby are correct.
