Question

How is displacement current relevant to MRI machines?

Options

• MRI machines require net charge movement through a capacitor gap to generate EM waves.

• MRI machines eliminate the magnetic effect of a time-varying electric field.

• MRI machines use only constant electric fields, so Maxwell's equations do not apply.

• MRI machines use EM waves whose generation is explained by Maxwell's equations, including displacement current.

Answer 1

MRI machines use EM waves. Their generation is explained by Maxwell's equations, which include displacement current.
