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. only abby is correct. b. both carl and abby are correct. c. only carl is correct. d. neither student is correct.

Explanation:

Carl is referring to the magnetic - field generation by an electric current, which is based on Ampere's law. Abby is referring to electromagnetic induction, where moving electrons (a current) through a magnetic field can induce an electric current. Both are fundamental principles in electromagnetism.

Answer:

B. Both Carl and Abby are correct.
