Question

What magnetic effect did Maxwell propose for a time-varying electric field?

विकल्प

• Only net charge movement through the gap can produce a magnetic effect.

• A time-varying electric field cannot produce a magnetic effect.

• A time-varying electric field must produce a magnetic effect.

• A constant electric field must produce displacement current.

Answer 1

Maxwell proposed that a time-varying electric field has a magnetic effect. He called this equivalent effect displacement current.
