Evaluate the statements below: (A) An emf can be induced by moving a conductor through a magnetic field. (B) An emf can be induced by altering the magnetic field.

Options

  1. ABoth A and B are false.
  2. BBoth A and B are true.
  3. CA is true, while B is false.
  4. DB is true, while A is false.

Correct answer

B. Both A and B are true.

Step-by-step solution

According to Faraday's law of electromagnetic induction, an induced emf is generated whenever there is a change in the magnetic flux linked with a circuit or a conductor. The magnetic flux = B A can be changed by altering the magnetic field B , changing the area A , or changing the angle . Moving a conductor through a magnetic field changes the area swept by the conductor, which induces a motional emf. Thus, statement A is true. Altering the magnetic field with time also changes the magnetic flux, which induces an
