Induction of Magnetic FieldsStudy Guide for Section 33.1Just as a changing magnetic field can induce an electric field, a changing electric field can inducea magnetic field. This induced field obeys the following equation:closedloopBL This equation is similar to Ampère's law, except that has been substituted in for thecurrent. This quantity is known as :displacement currentDisplacement current is measured in amps (A), just like real current. However, displacementcurrent is not actual current, it is just a changing electric field. We only think of it as current
